Admission
Identify and document the most recent lawful admission that begins the relevant §245(k) measuring period.
INA §245(k) • Burden of Proof and Documentation
Evidence to Prove INA §245(k) Eligibility
INA §245(k) can turn on a small number of days. A successful case therefore requires more than an assertion that the applicant was “out of status for less than six months.” The record should establish the most recent lawful admission, each period of lawful status, each employment authorization period, every alleged violation, and the exact number of countable days.
When the evidence suggests unauthorized employment or a status violation, the adjustment applicant bears the burden of establishing eligibility for the §245(k) exemption.
The strongest §245(k) filing converts the immigration history into a documented chronology that allows USCIS to verify every date in the 180-day calculation.

Direct Answer
What Evidence Should Be Submitted for INA §245(k)?
A well-documented §245(k) submission should establish the applicant's qualifying immigrant category, most recent lawful admission, lawful-status periods, employment authorization, actual employment dates, any other violations of admission, and a precise calculation showing that all covered violations after the relevant admission do not exceed 180 aggregate days.
The necessary evidence varies with the alleged violation. An I-94 may establish the admission and authorized stay. An I-797 may establish an extension or change of status. An EAD or petition approval may establish employment authorization. Payroll records may establish when an employment relationship actually began or ended.
No single document usually proves the complete case.
Burden of Proof
The Applicant Should Be Able to Prove Every Material Date
Violation
Identify the exact legal violation USCIS could allege and determine its beginning and ending dates.
Calculation
Calculate unique countable calendar days rather than relying on approximate months or general descriptions.
Do not wait for an RFE to reconstruct the chronology. If the filing itself reveals a possible status or employment problem, the §245(k) evidence can be submitted proactively with Form I-485.
Evidence Category One
Proving the Most Recent Lawful Admission
Primary Admission Records
- Form I-94 admission record
- Passport admission stamp
- Nonimmigrant visa used for the admission
- CBP travel history
- Passport biographic page
- Prior passports containing relevant entry stamps
Supporting Admission Records
- Airline itinerary or boarding record
- CBP records obtained through FOIA
- USCIS records identifying class of admission
- Petition approval associated with admission
- Consular visa issuance record
- Other reliable contemporaneous entry documentation
The most recent physical entry is not necessarily the most recent lawful admission. An ordinary advance-parole return, for example, generally does not replace the earlier lawful admission for §245(k).
Evidence Category Two
Proving Lawful Status After Admission
| Status issue | Potential evidence | What the evidence can establish |
|---|---|---|
| Original period of admission | I-94, passport, visa | Classification and authorized period following entry. |
| Extension of stay | I-797 approval, new I-94, filing receipt | Whether and when USCIS extended the authorized nonimmigrant period. |
| Change of status | I-797 approval and attached I-94 | Whether USCIS granted a new classification while the applicant remained in the United States. |
| F-1 or M-1 status | Forms I-20, SEVIS records, transcripts, enrollment records | Study, program participation, practical training, and possible status interruptions. |
| J-1 status | Forms DS-2019, SEVIS history, sponsor records | Program participation and authorized status periods. |
| Employment-based nonimmigrant status | I-129 approvals, employer records, I-94s | Authorized employer, classification, and validity dates. |
Evidence Category Three
Proving Employment Was Authorized
Employment Authorization Document
An EAD can establish a period of general employment authorization, but its exact validity dates must be compared with the actual employment period.
Petition-Based Authorization
H-1B, L-1, O-1, R-1, and other petition approvals may authorize employment only for the petitioning employer, classification, location, or period permitted by law.
Student Employment
OPT, STEM OPT, CPT, and other student employment require classification-specific evidence such as EADs, Forms I-20, SEVIS records, and employer documentation.
An approved immigrant petition does not itself authorize employment. Neither Form I-140 approval nor merely filing Form I-485 gives an applicant permission to work.
Evidence Category Four
Proving When Employment Actually Began and Ended
Employment Records
- Employer verification letters
- Offer letters and employment agreements
- Termination letters
- Payroll records
- Pay stubs
- Personnel records
- Timekeeping records where relevant
Financial and Tax Records
- Forms W-2
- Forms 1099
- Federal tax returns
- Bank deposits corresponding to compensation
- Business records for self-employment
- Invoices or payment records
- Other records showing compensated services
USCIS guidance treats unauthorized employment as tied to the existence of the unauthorized employment relationship, not merely the individual days on which the applicant physically performed work. The beginning and ending dates of that relationship therefore matter.
Evidence Category Five
Proving Compliance With the Terms of Admission
Students
Transcripts, enrollment records, Forms I-20, SEVIS history, practical-training authorization, and DSO records may establish compliance with F-1 or M-1 requirements.
Employment Classifications
Petition approvals, job descriptions, employer records, payroll documents, and worksite evidence can establish compliance with employer-specific status.
Other Nonimmigrants
Classification-specific records should establish that activities in the United States remained consistent with the terms and conditions of admission.
The Chronology
Build the §245(k) Case Date by Date
Admission → Status → Employment → Violation → I-485 → Adjudication
Every transition should have a date and supporting document.
| Date or period | Immigration event | Legal status | Employment | Countable under §245(k)? |
|---|---|---|---|---|
| January 10 | Lawful H-1B admission | H-1B | Authorized employer | No |
| June 30 | Employment terminates | Requires further analysis | Employment ends | Possible start of covered period |
| July 1–October 20 | Potential status violation | Analyze applicable rules | No unauthorized work | Calculate exact days |
| October 21 | Properly filed Form I-485 | Pending adjustment; not nonimmigrant status | Separate authorization required | Status-based accrual may stop for §245(k) |
This is only an example format. The actual legal start and stop dates depend on the applicant's classification, employment history, filings, statutory grace periods, agency decisions, and other facts.
Aggregate Calculation
Do Not Double Count Overlapping Violations
Status Violation Only
An applicant has 120 calendar days of failure to maintain lawful status and no other non-overlapping covered period. The aggregate is 120 days.
Status + Work on Same Days
The applicant is both out of status and working without authorization during the same 120-day period. Those overlapping calendar days are not ordinarily counted twice.
Separate Periods
The applicant has 120 covered days followed later by a separate 50-day covered period. The aggregate becomes 170 days.
The statutory question is whether the aggregate period exceeds 180 days. The applicant does not receive 180 days for unlawful status plus another 180 days for unauthorized employment.
Proving a Negative
What If USCIS Believes Unauthorized Employment Occurred?
Identify the Alleged Employer or Activity
Determine exactly what work USCIS believes occurred, the employer or business involved, the dates, and why USCIS considers the activity employment.
Respond With Specific Evidence
Relevant evidence may include payroll records, tax documents, bank statements, employer declarations, business records, contracts, school records, or other documentation showing that the activity was authorized or was not employment.
A bare statement that the applicant “did not work” may be inadequate when government records or other evidence suggest employment. The response should address the underlying facts directly.
Missing Records
What If the I-94, Passport, or Employment Records Are Missing?
Government Records
CBP and USCIS records may help reconstruct admissions, petition approvals, status filings, and other immigration events.
Employer Records
Former employers may be able to provide payroll histories, employment verification, termination dates, or copies of immigration filings.
Secondary Evidence
Tax records, bank records, travel documents, school records, contemporaneous correspondence, and declarations may help establish facts when primary records are unavailable.
Explain missing evidence rather than ignoring the gap. A declaration can identify what records once existed, why they are unavailable, what efforts were made to obtain them, and what secondary evidence establishes the same fact.
RFE and NOID Preparation
USCIS May Ask for Specific §245(k) Evidence
RFE
USCIS may request documents establishing lawful admission, status maintenance, employment authorization, or the dates of possible violations.
NOID
A Notice of Intent to Deny may identify evidence suggesting more than 180 days of violations or an inability to satisfy another §245(k) requirement.
Response Strategy
The response should distinguish factual errors, legal errors, excluded periods, overlapping periods, authorized employment, and any incorrect starting or ending dates.

Frequently Asked Questions
INA §245(k) Evidence FAQs
What documents prove my last lawful admission?
Common evidence includes Form I-94, passport admission stamps, CBP travel history, the visa used for admission, and related immigration records.
How do I prove employment was authorized?
Depending on the classification, evidence may include an EAD, petition approval, I-94, Form I-20, SEVIS records, employer-specific approval notices, and other documents establishing the scope and dates of work authorization.
Should I submit a §245(k) calculation with Form I-485?
When the record contains an apparent status or employment violation, a clear chronology and precise calculation can help demonstrate why the applicant remains within §245(k).
Do I count only the days I physically worked?
Not necessarily. USCIS guidance generally examines the period of the unauthorized employment relationship rather than only individual shifts or hours actually worked.
Can the same day count twice if I was both out of status and working without authorization?
Overlapping violations generally do not cause one calendar day to be counted more than once in the aggregate §245(k) calculation.
What if important records are missing?
Government records, former employer records, tax documents, bank records, school records, and other secondary evidence may help reconstruct the chronology. The filing should explain material missing evidence and efforts to obtain it.
