I came to USA in 1989 but after but after the 2 years to adjust the temporal card to the permanent card my parents did not do it

I assume that you and your mother entered the U. S. as conditional residents based upon your mother’s marriage to a U. S. citizen, and that you somehow did not have the conditional basis of your residence status removed. If your mother’s marriage was bona fide in the sense that she and your stepfather are living or lived together as man and wife after her arrival to the States, and you were otherwise qualified to have your conditional status changed at the time to permanent status, you may still be able to file an I-751 application to remove the conditional basis of your residence status if one was never filed previously or even if one was filed. You would have to explain the lateness of your filing and it would be up to the U.S.C.I.S. service center examiner and /or his or her supervisor to excuse the lateness and approve your application, or to send your case onwards for hearings in the immigration court. You state that the immigration office told you that the adjustment from temporal to permanent resident was never completed. Does that mean that the I-751 was submitted? If so, you can point out that fact in support of a late application.
