Most permanent residents renew an expiring or lost 10-year green card with Form I-90, which costs $465 by paper as of October 2026. Two-year conditional cards are different: they require Form I-751 or I-829. Long trips abroad can put residence at risk, and a reentry permit can help for absences of a year or more.
This guide is for lawful permanent residents whose green card is expiring, lost, damaged or wrong, and for residents who plan to spend long periods abroad. It explains which form fits which situation, how conditional residents differ, how reentry permits work, and when travel can put permanent residence at risk.
A key point first: for most people, permanent resident status does not expire when the card does. The 10-year card is proof of status. Conditional residents with a 2-year card are the exception, because their status itself ends unless conditions are removed.

| Situation | Form | Fee (as of Oct. 2026) |
|---|---|---|
| 10-year card expiring within 6 months, or already expired | I-90 | $465 paper ($415 online) |
| Card lost, stolen, damaged, or legal name changed | I-90 | $465 paper ($415 online) |
| Card has an error made by DHS, or card was never received | I-90 | No fee in those cases |
| 2-year card based on marriage | I-751 | $750 |
| 2-year card based on EB-5 investment | I-829 | Changes Nov. 30, 2026 under a new EB-5 fee rule; see USCIS fees |
| Planning to be abroad 1 year or more | I-131 reentry permit | $630 |
Fees are from 8 CFR 106.2; the $50 online discount comes from 8 CFR 106.1(g). Children who got a card before age 14 generally must replace it after turning 14; there is no I-90 fee if the existing card would expire after the 16th birthday. The I-829 fee is an exception: after a November 2025 court decision, USCIS returned to the pre-April 2024 EB-5 fees ($3,750 for Form I-829), and a DHS final rule (91 FR 61940) sets the fee at $5,000 for filings postmarked on or after November 30, 2026. Our fee calculator totals the fees for your forms.
Renewing does not reopen the original case in most situations, but USCIS does run background checks. People with arrests or convictions since getting the card should talk to an attorney before filing, because a renewal can bring those records to the agency's attention.

A conditional card cannot be renewed with Form I-90. Conditional residents must ask USCIS to remove the conditions during the 90 days before the card's expiration date:
A timely filing produces a receipt notice that extends conditional status for a set period past the card's expiration while the petition is pending. USCIS lists the current extension period on its Form I-751 and Form I-829 pages; carry the receipt notice with the card. Our deadline calculator shows your 90-day filing window. Missing the deadline without good cause can end status automatically and lead to removal proceedings.
A green card allows return to the United States after travel, but it is not a guarantee. At the border, CBP looks at whether the person still lives in the United States.
Permanent residence can be lost by abandonment even without a single long trip. Officers look at intent and ties: where the person works, files taxes as a resident, keeps a home, holds bank accounts and has family. Filing U.S. taxes as a nonresident is a particularly strong sign of abandonment. A resident who is pressured at the border to sign Form I-407 (record of abandonment) is not required to sign it and can ask for an immigration judge to decide instead.
If CBP questions whether you have abandoned residence, stay calm, answer truthfully and ask for a copy of anything you are asked to sign. Contact an attorney as soon as possible. See know your rights.
A reentry permit helps a resident who plans to be abroad for 1 to 2 years. It shows intent to keep U.S. residence and can be used to return instead of a visa. Key points:
Employers, motor vehicle agencies and airlines may ask for proof of status before the new card arrives. Options as of October 2026 include:
Keep copies of the old card, the receipt notice and the biometrics notice together, and carry them when traveling.
Many long-time residents who are already eligible for citizenship choose to naturalize instead of renewing the card again. Citizenship ends the need to renew, removes abandonment risk from long trips and allows the person to sponsor more relatives. However, a pending N-400 does not extend an expiring card. If the card will expire before the naturalization oath, file Form I-90 as well, or ask USCIS for temporary evidence of status. A naturalization case also involves a closer review of the person's history than a card renewal, so anyone with a past arrest or immigration problem should get advice first.

For holders of a 10-year card, no. Status continues, but you should renew the card with Form I-90 because it is your proof of status for work, travel and identification. Conditional residents with a 2-year card are different: their status ends unless they file Form I-751 or I-829 on time.
As of October 2026, Form I-90 costs $465 by paper and $415 if filed online. There is no fee if the card has an error made by DHS or if you never received a card USCIS issued. Check the USCIS fee schedule before paying, because fees can change.
An expired card alone may cause problems with airlines and at the border. USCIS has said an I-90 receipt notice, presented with the expired card, serves as temporary proof of status. Residents who need to travel soon may also ask USCIS for an appointment to get a temporary stamp in their passport.
There is no fixed safe number, but trips over 6 months can draw questions about abandonment, and a stay of 1 year or more without a reentry permit generally means the card can no longer be used to return. A reentry permit, filed before leaving, can cover absences of up to 2 years.
It is an immigrant visa for permanent residents who stayed abroad longer than allowed for reasons beyond their control, such as a serious illness. The person applies at a U.S. consulate, pays a $180 State Department fee for the determination, and must show they intended to keep U.S. residence throughout.
