Is the filing of I-829 based on the date of I-485 submission or the date when the conditional green card is issued?

You become a conditional permanent resident the day your I-485 was approved. You should submit an e-request: typographic error. Correct your green card first and then submit the I-829 petition within the 90-day period immediately preceding the second anniversary of obtaining conditional permanent resident status.

I-829 should be filed in the 90-day window prior to the two-year anniversary of receiving the conditional residence (the Resident Since Date on your green card). I recommend filing the I-90 to correct the date on the PR card and filing the I-829 in the 3-month window before your conditional residency expires, assuming USCIS sent you the correct card.

You should file on the correct date.

You should get the green card date corrected regardless of how long it takes.

It is 90 days before your condition expires, which is normally 90 days before the 2-year anniversary of the approval date.

The card should have been corrected with the correct start date of conditional residency.

File the I-90 and wait for the new green card. USCIS should correct its error.
