Even though I am married to a US citizen with all the documents and evidence to prove it, will my violation of my OPT status affect my filing?

Generally, a foreign national who entered the U.S. lawfully and with inspection (such as with F1 OPT status), and who then becomes married to a U.S. citizen, remains eligible for a marriage-based Adjustment of Status application notwithstanding that he/she may have overstayed an initial visa or have been employed without authorization. The filing of a marriage-based case should include an application for an Employment Authorization Document (an "EAD" or "work permit") which will authorize employment while the Adjustment of Status case remains pending. An EAD associated with OPT status is for specified employment as part of a student's training, while an EAD associated with an Adjustment of Status case is for any lawful employment. An employer should not accept as evidence of authorization for employment an OPT-related EAD that does not correspond to the employment contemplated by that employer. Of course, there are many other details involving eligibility for a marriage-based Adjustment of Status application in the Immediate Relative visa category, and involving eligibility for employment.
