Applying for U.S. residency (a Green Card) is a meticulous process that demands careful documentation.
Missing even a single form or signature can delay your application by months or lead to a denial.
This guide lists every essential document you need, explains why it matters, and shows you how to prepare a flawless application package.
1. Core Identity & Civil Documents
These prove who you are, where you were born, and your family relationships.
- Birth Certificate: Official long-form copy showing parents' names. Must be translated into English by a certified translator.
- Passport: Valid, unexpired passport (biometric page). Include all pages with visas, entry/exit stamps.
- Marriage Certificate (if applicable): For spouse-based petitions. If previously married, submit divorce decrees or death certificates.
- Adoption Decree (if applicable): Finalized adoption papers naming the child and adoptive parents.
2. Financial Support Documents (Affidavit of Support)
USCIS requires proof that you won't become a 'public charge'. The sponsoring petitioner must file Form I-864.
Key requirement: Sponsor’s income must be at least 125% of the Federal Poverty Guidelines (based on household size).
- Tax returns and W-2s from the last 3 years.
- Recent pay stubs (last 6 months).
- Employment verification letter (position, salary, start date).
- Proof of assets (savings, property, stocks) if income is insufficient.
3. Immigration & Travel History
USCIS needs to verify your lawful entry and any prior immigration violations.
- Form I-94 Arrival/Departure Record (downloadable from CBP website).
- All prior U.S. visas (even expired ones).
- Employment Authorization Documents (EAD) or Advance Parole if previously held.
- Any notices of deportation, removal, or overstay (if applicable, include explanation).
4. Medical Examination (Form I-693)
Completed by a USCIS-designated civil surgeon. Includes vaccination record (MMR, flu, Tdap, etc.).
Do NOT open the sealed envelope.
Tip: Submit I-693 together with your main application to avoid a Request for Evidence (RFE).
5. Application-Specific Forms & Evidence
Depending on your category, add:
- Family-based (I-130): Proof of bona fide relationship (photos, joint leases, affidavits from friends).
- Employment-based (I-140): Labor certification (PERM), job offer letter, degrees, and experience letters.
- Asylee/Refugee (I-589): Country conditions reports, personal affidavit of persecution.
- VAWA (self-petition): Proof of battery or extreme cruelty (police reports, medical records, witness statements).
6. Photographs & Filing Fees
- Two identical passport-style photos (2x2 inches, white background, taken within 30 days).
- Check or money order for Form G-1450 (if paying by credit card).
In summary, create a checklist, hire a certified translator for non-English documents, and make copies of everything before mailing.
A complete document set is your best defense against delays.
