What should I do if I have applied for naturalization and my permanent resident card (green card) will expire soon?

While a person's legal permanent resident status does not expire except by naturalization or termination, legal permanent residents must always have valid, unexpired proof of legal permanent residence.  Applying for naturalization does not change this requirement.  However, as of December 12, 2022, naturalization applicants who correctly file Form N-400 will receive a Form N-400 receipt notice, which automatically extends the validity of the green card for 24 months from the "Card expiration" date upon presentation.  This receipt notice must be presented to show that your green card, which is proof of your legal permanent resident status, for example for employment or travel authorization purposes, has been extended.  If you have received a Form N-400 receipt notice that automatically extends the validity of your green card, but it has been lost or destroyed, then you must usually file Form I-90 to renew your expiring green card.
