How can i get green card with overstayed waiver visa (esta) and lost I-94 form, if i'm getting married with my boyfriend?

In order to locate a record of entry, you can file form I-102 for a replacement I-94 or I-94 W with U.S.C.I.S. Once you have that, you may be able to file for adjustment of status through a US citizen spouse. I do note that there has been trouble in the past with adjustment of status for those who came in and overstayed under the visa waiver program, although it is my understanding at this time that U.S.C.I.S. will continue processing cases of this type. You may wish to consult with a local attorney to see what the local practice of the U.S.C.I.S. field office is in dealing with your particular kind of case.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
