Filling Out Form I-140 for a NIW: A Field-by-Field Walkthrough

Before You Open the Form

Assemble the following before you start typing into any PDF field. Working from incomplete records is the most common reason people abandon a half-filled form and start over.

Documents to have on hand

1. Current Form I-140 edition. Download it fresh from uscis.gov rather than reusing a copy someone sent you — USCIS rejects submissions on outdated editions, and edition dates change without much notice.
2. A-Number, if one has ever been assigned (from a prior immigration filing, EAD, or green card application). If none exists, leave that field for N/A rather than guessing.
3. Passport, to copy your legal name exactly as it appears there — this is the name USCIS will expect throughout the petition.
4. Prior visa and entry history: visa stamps, I-94 records (available at i94.cbp.gov), and any prior petitions filed on your behalf.
5. Employer or self-petitioner details. If an employer is involved, gather their legal business name, FEIN, and address. If you are self-petitioning, you will not have employer information to enter — more on that below.
6. Current filing fee. Confirm the exact amount on uscis.gov immediately before filing; fees change periodically and using a stale number can delay processing.

If you are self-petitioning

Everywhere the form says "Petitioner," that refers to you. Do not leave those fields blank waiting for an employer's information, and do not enter a company name in that section — NIW petitions are structured so the beneficiary and petitioner can be the same person.

Part 1: Petitioner Information

Petitioner type

The first question asks whether the petitioner is a company/organization or an individual. A self-petitioner filing under the national interest waiver selects the option indicating an individual petitioning on their own behalf (commonly phrased as "yourself" on the form). Do not select an employer-type option and then also list yourself as beneficiary — the two roles collapse into one person for a self-petition, and the form fields should reflect that consistently.

Legal name

Enter your name exactly as it appears on your passport — same order, same spelling, no added middle names or nicknames not printed there. If your passport lists a single name or unusual order, replicate it precisely rather than reformatting to a Western first/last convention. USCIS compares this against your passport and prior filings; mismatches trigger requests for clarification.

Mailing address

Use a mailing address where you can reliably receive USCIS notices, not necessarily your residence. Include suite, unit, or apartment numbers on the designated line — omitting these is a frequent cause of misdelivered notices. If someone else's name should appear for delivery purposes (a relative, attorney, or workplace mailroom), use the "in care of" (C/O) line rather than folding that name into your own.

Common errors

• Reversed given/family name order
• Missing suite/unit numbers
• Address that doesn't match other concurrently filed forms (I-485, I-131) without explanation
• Nicknames or anglicized names not matching the passport exactly

Part 2: Classification Requested

Part 2 is where the petition tells USCIS which employment-based category applies. For a national interest waiver, this is not a separate classification from EB-2 — it is a modifier attached to it. Get this checkbox wrong and the entire petition can be routed, and reviewed, as something it isn't.

Selecting the Right Box

Current versions of Form I-140 list several EB-2 options separately: a plain "member of the professions holding an advanced degree or an alien of exceptional ability" box, and a distinct box for the same category "seeking a national interest waiver." Read every option in Part 2 before marking one — do not assume the first EB-2-labeled box is correct. Select the box that specifically references the national interest waiver. Checking the plain EB-2 box instead signals a standard labor-certification-based petition, which implies an approved or pending Form ETA-9089 that a self-petitioner will not have.

Common Mistakes

• Checking an EB-1 box (extraordinary ability, outstanding researcher, or multinational executive) because it appears above EB-2 on the form — these carry entirely different eligibility standards and evidentiary requirements.
• Marking plain EB-2 without the waiver designation, which can trigger a request asking for the missing labor certification.
• Leaving the box unmarked, assuming the classification is "obvious" from attached evidence.

Verify the exact wording against the current edition on uscis.gov before marking anything, since form layouts are revised periodically and box numbering can shift between editions.

Part 3 through Part 5: Beneficiary and Employment Details

Part 3: Biographic Information

Enter the beneficiary's name, date of birth, country of birth, and country of citizenship exactly as they appear on the passport and any prior USCIS filings (I-94, prior petitions, EAD). If the beneficiary has used other names — maiden name, alternate transliterations — list them under "other names used" rather than omitting them; an unexplained mismatch between documents is a common source of delay.

Part 4: Beneficiary's Current Immigration Status and Entry History

Record the current status (F-1, H-1B, J-1, etc.), the I-94 number, and the most recent U.S. entry date and admission classification. Pull this directly from the CBP I-94 website (i94.cbp.dhs.gov) rather than from memory — printouts should match what is entered field for field. If there have been multiple entries or status changes, use the most recent admission unless the form instructions specify otherwise.

Part 5: Proposed Employment

Self-petitioners fill in job title, duties, and location as their own intended endeavor, described briefly — a sentence or two summarizing the field and objective (e.g., "Research and development of solid-state battery materials for grid-scale storage"). This wording should track the language used in the business plan or research statement, but should not attempt to compress the full argument for national interest onto the form. The form is a data record; the persuasive case belongs in the personal statement and supporting letters. Keep terminology consistent across both documents to avoid an officer flagging a discrepancy between form and evidence.

Part 6: Basic Information About the Proposed Employment

This part asks for the job title, occupational classification, wage, and worksite tied to the proposed endeavor. Answer it as though the endeavor were a real position, even when there is no employer.

Job Title

Use a specific, descriptive title that matches the language in your personal statement and CV (e.g., "Senior Battery Materials Researcher," not "Scientist"). Avoid inventing a title that appears nowhere else in your evidence — an officer cross-checking Part 6 against your statement will notice a mismatch.

SOC Code Lookup

Go to onetonline.org and search your field or job title to find the matching Standard Occupational Classification (SOC) code and title. Enter the six-digit code and its official title exactly as ONET lists them. If your work spans two plausible codes, choose the one whose task list most closely matches your actual proposed activities, and keep a printout of the ONET page in your records.

Wage Level

If a wage level entry is requested, check the current Department of Labor wage data via the FLC Data Center (flcdatacenter.com) for your SOC code and intended area of employment. Enter the level and figure that correspond to your actual location and experience.

Worksite Location

Enter the city, state, and ZIP code where the work will actually occur. Self-petitioners without a fixed employer should list the location tied to their research, practice, or business activity, described consistently with the geographic scope stated in their personal statement.

Signatures, Interpreter and Preparer Sections

Petitioner Signature

The petitioner signs and dates the form in the designated signature block — for a self-petitioner, that means signing as the beneficiary/petitioner, even though a separate beneficiary section exists elsewhere on the form. An unsigned or undated form is one of the most common reasons for outright rejection rather than an RFE, so check this before mailing, not after.

Interpreter Certification

Complete the interpreter section only if someone read or translated the form to the petitioner in a language other than English. The interpreter enters their name, business or organization (if any), address, phone number, and the language used, then signs and dates. If no interpreter was involved, leave this section blank — do not fill it in as a formality.

Preparer Section

If anyone other than the petitioner filled out the form — a colleague, friend, or paid preparer — that person completes the preparer section with their name, business name and address (if applicable), and signs and dates. This applies whether or not the preparer is an attorney; if the preparer is an attorney or accredited representative, they also complete Form G-28 separately. If the petitioner filled out and filed the form entirely without assistance, this section stays blank — checking any box or entering information here when no one helped can create confusion about who is representing the petitioner.

Attachments and Cross-Referencing Evidence

Form I-140 is short; the substance of an NIW filing lives in the attachments. An officer should never have to guess which document supports which claim on the form. Build an index before you assemble the final packet.

Numbering exhibits

1. Assign each supporting document a sequential exhibit number: Exhibit 1, Exhibit 2, Exhibit 3, and so on — cover letter, personal statement, degree certificates, publications, citation records, reference letters, evidence of the proposed endeavor, and so forth.
2. Label the first page of each exhibit with a tab or header reading "Exhibit X."
3. Paginate the entire packet continuously (page 1 through the final page), independent of exhibit numbering, so you can cite exact page numbers in your cover letter.

Building the cross-reference table

In your cover letter, include a table mapping each relevant I-140 part or item to its supporting exhibit:

Why this matters

A clear index lets an adjudicator verify each form entry against evidence without searching. Missing or vague cross-references are a common source of delay, since officers may issue a request for evidence simply to locate documentation that was filed but not indexed.

Final Review Checklist

Before printing and mailing, go through the form line by line against this list rather than relying on memory.

Completeness

• Every question has an answer. Use "N/A" or "None" where nothing applies — never leave a field blank. Blank fields are a common reason officers issue a Request for Evidence (RFE), since USCIS cannot tell whether a blank means "not applicable" or "overlooked."
• Part 2's classification box is checked correctly for the NIW category, not a generic EB-2 or EB-1 box.
• Dates are internally consistent: entry dates match I-94 records, employment start dates match the letter or business plan, and nothing predates the beneficiary's actual U.S. arrival.

Signatures and Fees

• The petitioner's signature is original (or otherwise valid per current USCIS instructions) and dated within the validity window stated in the form instructions — check uscis.gov, as this can change.
• The filing fee matches the current fee schedule on uscis.gov, not a figure from a prior filing or another petitioner's experience. Fees change without much notice.

Evidence and Records

• Every exhibit referenced in the cover letter table actually appears in the package, in the stated order.
• No exhibit is cited in the narrative but missing from the attachments, and no attachment is unreferenced.
• A complete copy of the entire package — form, letter, and exhibits — is retained before mailing, along with proof of mailing or delivery tracking.

A final pass reading the form aloud, part by part, against the exhibit table catches most inconsistencies before they become RFEs.
