The USCIS mistake that costs the most
Filing Form I-485 before your priority date is current means automatic rejection, and you forfeit the filing fee. That fee was $1,440.
Check the Department of State’s monthly Visa Bulletin at travel.state.gov before you file anything. Your priority date is set when your initial petition was filed, and it is your place in the queue.
Priority dates, and who does not need one
Your priority date is established when your initial petition, either Form I-130 for family or Form I-140 for employment, is filed. The monthly Visa Bulletin shows which priority dates are current, meaning you can proceed to file Form I-485.
Immediate relatives do not wait at all. That means spouses of United States citizens, unmarried children under 21 of citizens, and parents of citizens where the citizen is 21 or older.
Everyone else is in a preference category and must wait for their priority date to become current. That covers all other family relationships and effectively all employment based categories.
Processing times
| Application | Typical processing |
|---|---|
| Family based green card, after priority date is current | 8.7 months |
| Employment based green card | 7 months |
| Naturalization | 5.5 months |
| Work permit, most categories | Under 1 month |
| Asylum seekers waiting to apply for a work permit | 365 days after filing |
Work permits now process in under a month for most categories, considerably faster than in previous years. That makes timing more important, not less, because a badly timed application can still leave a gap in your work authorisation.
Green card applications, Form I-485
Adjustment of status lets eligible people become lawful permanent residents without leaving the United States. It is open to family sponsored applicants with an approved I-130, employment based applicants with an approved I-140, diversity visa lottery winners, asylum seekers one year after an asylum grant, and refugees one year after admission.
What everyone needs
- Form I-485
- A copy of government issued photo identification
- Birth certificate with a certified English translation
- Medical examination, Form I-693, by a USCIS approved civil surgeon
- Two passport style photographs
- Copy of your arrival and departure record, and Form I-94 showing current status
Family based, additionally
- Copy of the approved Form I-130
- Proof of your relationship to the petitioner
- Sponsor’s Form I-864, Affidavit of Support
- Sponsor’s tax returns for the last three years
Employment based, additionally
- Copy of the approved Form I-140 where required
- Employment verification letter
- Form I-864 or I-864EZ if needed
Filing forms together saves time and money
Filing related applications as a packet lets them process simultaneously. Common combinations are I-485 with I-765 and I-131, giving you a green card application alongside a work permit and travel document; I-130 with I-485 and I-765 for immediate relatives only; and multiple I-485s for a principal applicant filing with spouse and children.
The advantages are real: a single filing fee covering related applications, coordinated processing, work authorisation while the green card is pending, and advance parole allowing international travel.
Only file a packet when every form is eligible at the same time. Filing prematurely wastes a significant amount of money.
Naturalization: the requirement people confuse
There are two separate residency tests, and they are not the same thing.
Continuous residence means maintaining your permanent home in the United States. Five years for most applicants, or three if married to a citizen. An absence of six months or more creates a presumption that residence was broken. An absence of a year or more almost always breaks it.
Physical presence is the total number of days you were actually inside the country. Thirty months for five year residents, eighteen months for three year residents.
You can satisfy one and fail the other. Frequent short business trips can keep your continuous residence intact while quietly pushing you below the physical presence threshold. Keep detailed records of every trip: passport stamps, airline tickets, hotel receipts and work travel documentation.
Full eligibility requirements
- At least 18 years old
- Permanent resident for 5 years, or 3 if married to a United States citizen
- Physically present for at least half the required period
- Continuous residence for the required period
- English ability in speaking, reading and writing
- Pass the civics test on history and government
- Good moral character, and attachment to the Constitution
Documents for Form N-400
Your permanent resident card front and back, current marriage certificate if applicable, divorce decrees from previous marriages, tax returns for the last five years or three if married to a citizen, and Selective Service registration for males who were aged 18 to 25 during the registration period.
Work permit categories
You must identify your exact category number on the application. The most common are:
| Category | Who | Key requirement |
|---|---|---|
| (a)(5) | Asylees | Wait 365 days after filing a complete asylum application, unless you hold a Recommended Approval notice |
| (c)(9) | Adjustment of status applicants | File immediately with your I-485, valid until the green card decision |
| (c)(3)(B) | Students on Optional Practical Training | Complete degree requirements first, apply within 90 days, valid 12 months with STEM extensions available |
| (c)(26) | H-1B spouses | The H-1B holder needs an approved I-140 or to be in their sixth year |
Documents: what counts and what does not
Certified copies means documents certified by the issuing agency, notarised copies of originals, or copies certified by a United States consular officer abroad. Regular photocopies, faxes and digital printouts of online documents do not qualify.
Translations can be done by a professional service, a certified court interpreter, or anyone fluent in both languages, including you. The translation must cover the entire document and carry the translator’s certification statement, name, signature, contact details and a statement of their qualifications.
Photographs
2 by 2 inches, head between 1 and 1.375 inches from chin to crown, white or off white background, taken within 30 days of your application, front facing with both eyes open and a neutral expression. No glasses unless medically necessary with a signed statement. Religious head coverings are permitted where worn daily.
The medical examination
Search the USCIS website for an authorised civil surgeon near you, then book after completing Form I-485. Bring your vaccination records and medical history. Expect $200 to $500 depending on location, and note this is rarely covered by insurance.
Required vaccinations include COVID-19, measles, mumps and rubella, polio, tetanus and diphtheria, pertussis, haemophilus influenzae type B, hepatitis A and B, varicella, influenza, pneumococcal disease, rotavirus and meningococcal disease.

Frequently asked questions
What is a priority date?
It is set when your initial petition is filed and determines your place in line for a green card. Check the monthly Visa Bulletin at travel.state.gov to see whether yours is current.
What happens if I file too early?
Filing Form I-485 before your priority date is current results in automatic rejection and forfeiture of the filing fee.
