This petition must be filed by all conditional residents within the 90-day window before expiration of their conditional green card. Not filing the petition or not filing it during the required 90-day period can result in revocation of the lawful permanent status and can lead to deportation.
I-751 petition was previously filed at the California and Vermont Service Centers. Now, petitioners must send Form I-751 to a USCIS Lockbox facility. However, the California, Nebraska, Vermont, and Texas Service Centers will be the adjudicating offices. When filing at a Lockbox facility, petitioners have the option to pay the fee with a money order, personal check, cashier’s check, or credit card.
