What is the I-751 for?
Conditional resident cards are valid for two years, not ten. Look at the dates printed on your card: that is where the difference shows. If USCIS grants the petition, the residence stops being conditional.
The instructions describe two routes: filing the petition together with the spouse, or asking USCIS to stop requiring that signature when that is not possible — through divorce, widowhood, or abuse.
It is a different filing from a card replacement, even though both end in a new card. Which route is yours is a legal question, sometimes a delicate one, that Paso Libre does not answer.
Who usually files it?
- According to the USCIS instructions: a conditional resident married to the citizen or resident who petitioned for them, together with their spouse, in the 90 days before the card expires.
- According to the USCIS instructions: a conditional resident who can no longer file jointly and requests a waiver for the reasons the instructions list.
- According to the USCIS instructions: children who received conditional residence at the same time are included on the same petition.
