What to expect next (mailing & timing)

After USCIS approves an AOS the agency typically mails a welcome notice and then the physical Permanent Resident Card (Form I-551) to the address on file.
If the applicant moved before the card arrives, the address should be updated with USCIS immediately to avoid lost mail. If the card does not arrive within the timeframe
stated in the approval/welcome notice, use USCIS online tools (myUSCIS/e-Request) to check delivery or report a missing card. 

Immediate actions (0–14 days)

  • Scan & file. Scan the approval notice (Form I-797) and any accompanying USCIS correspondence and put the copies in the secure client file.
  • Confirm mailing address. If the client moved recently, file an address change with USCIS and monitor mail carefully. 
  • Check SSN status. If the client does not already have a Social Security number, USCIS/SSA procedures often result in SSA issuing one automatically; otherwise, submit Form SS-5 to SSA. (See SSA guidance.) 
  • Advise employer/education providers. Provide copies of the green card once received as proof of work authorization or lawful status when required.

Travel & reentry (what to plan)

Lawful permanent residents may travel, but absences of 6 months or more can raise questions about abandonment of residence; absences of 1 year usually require a reentry permit
or risk additional scrutiny at the border. If the client previously used Advance Parole to travel while the I-485 was pending, confirm the AOS approval and advise carrying
all supporting documents on return. For longer trips, consider filing Form I-131 (reentry permit) before departure. 

In family-based approvals the sponsor’s Form I-864 typically remains enforceable after approval. Counsel should keep sponsor financial records (tax returns, W-2s) in the case file
and advise both sponsor and beneficiary about the continuing contractual nature of the affidavit of support.

Documents to keep (long-term)

  • Physical Permanent Resident Card (I-551) — keep original safe.
  • Approval notice (I-797) and scanned copies of all USCIS correspondence.
  • Copies of I-130/I-140/I-485 packages and supporting docs (I-693, I-864, civil-surgeon contact).
  • Passport pages with admission stamps and I-94 records.
  • Tax returns and employment records used to support sponsorship evidence — retain for several years.

Path to naturalization

For most LPRs the clock toward U.S. citizenship begins on the date permanent resident status is granted; the typical eligibility period is 5 years (3 years if married to a U.S. citizen),
subject to physical presence and good moral character requirements. Track the exact eligibility date and document continuous residence. (See USCIS naturalization guidance.) 

Red flags & follow-up actions

If anything about the approval or the mailed card looks incorrect (name mismatch, wrong A-number, or card sent to wrong address), do not destroy any documents. Submit an e-Request
to USCIS and contact counsel immediately. In rare cases USCIS may later take administrative action if material issues (fraud or clear ineligibility) surface — keep client contact info current
and be ready to respond to any USCIS requests. 

Frequently asked questions

Q — When will the green card arrive?

Timing varies by field office and mail. USCIS sends a welcome notice then the physical card; if it does not arrive in the timeframe listed, submit an e-Request. 

Q — Can USCIS reverse an approval?

Yes — approvals can be reviewed and in limited circumstances revoked if fraud or material misrepresentation is later discovered. Keep thorough records and be ready to respond. 

Q — Can the client travel while waiting for the green card?

Short trips are generally fine; long trips risk abandonment and may require a reentry permit. If the client lacks the physical card but needs to travel urgently, counsel can advise about temporary I-551 stamps or other remedies.
