What happens when my Green card expires:
When your Green card expires, it does not mean your legal status as a Permanent resident of the United States expires. Only the validity of the proof has expired. It is required by law to carry a valid Green card at all times and hence it is best to renew the Green card before it expires.
Am I eligible to apply for citizenship with an expired Green card?
If you have decided to apply for citizenship, you must first check if you are eligible for naturalization. If you are eligible for naturalization, you can apply for citizenship even though your Green card has expired. The Green card is just an evidence of your permanent resident status and expiry of the Green card does not mean you permanent resident status has changed.
If your Green card is valid for more than six months, you can apply for the citizenship without renewing your Green card. But if the validity of your Green card is less than six months, you are required to first renew the Green card using the I-90 Application Form before you apply for citizenship. After you receive the receipt for the Green card renewal application, you can apply for the citizenship application. This is because you need to submit a copy of your valid Green card when you apply for the naturalization process. In case of an expired green card, you can submit a copy of the I-90 application receipt notice. This will prevent legal complications and speed up the citizenship application process than applying with an expired green card.
Why should I renew my Green card even though I qualify for the Citizenship Application?
The naturalization process is a very long process which takes many months from the time of applying to complete the process with the citizenship ceremony. As a responsible permanent resident of this nation, you must carry your valid Green card with you at all times. Even though you can apply for citizenship with an expired Green card, it is highly recommended that you renew your Green card. A valid Green card is required for employment, to receive any government benefits, and to travel outside the U.S and enter the country without any problems.
