I got my conditional green card on July 20th It took about 6 months from the submission of AOS application to receiving conditional green card. Do I file for removal of conditional green card within 90 days of our 2 years anniversary? I just want to make sure that I dont need to worry about anything till then. How much its going to cost to file for removal of conditional GC?

P.S. Speical thanks to all of people here who help everybody and you guys really helped me a lot with my AOS application. Without your help, I probably would spend lots of money on lawyers. Thank you very much.

Next is filing to remove conditions within 90 days of the card expire.

Just to clarify! Did you mean to apply for removing conditions 90 days before the GC expires.
"Within" could mean either way.

Hi,

There is a expiry date found in your greencard. 90 days before that expiry date you must file to remove your conditional status (This is what the Immigration Officer told me so that they have enough time to process our papers before our greencard expire). Fee to remove conditional status or any other fee usually change from time to time. Be sure to to update yourself regarding the fee before submitting your application. You can found the fee here in visa journey, you can browse also in the USCIS website or call the nearest USCIS where you live. Congrats!

90 days WITHIN the card expires. if you're idealistic, you file exactly 90 days before, but that's a personal thing. the I-751 Instructions say: "if you are filing this petition jointly with your spouse, you must file it during the 90 days immediately before the second anniversary of the date you were accorded conditional resident status. This is the date your conditional residence expires"
for now it costs $ 545.00 (filling + biometrics), and the only way it could go is up, so don't hope at anything less than that.

and you do need to worry about something: not throwing away ANYTHING that could be evidence of a bonafide marriage in the next 2 years. you'll need it when removing conditions.

congrats on your AOS approval! enjoy the lack of paperwork while it lasts!
