Legal Question in Immigration Law in California

There is no extension for a conditional resident card. If you are referring to removing the condition on the card, using form i - 751, then you just need to submit the jointly signed form, joint documents, and the filing fee. Your joint documents should include a copy of your most recent, jointly filed federal income tax return. It should not matter if you did not work last year, as long as your tax return was jointly filed with your spouse.
