Hello, I am a US citizen and my father lives in The Dominican Republic, I would like to know if I can petition for him?

Marriage fraud is one of the forever bars for which there is no waiver. Any further petition is deniable unless the applicant is able to persuade U.S.C.I.S. and the US consular officer that there was actually no fraud. Such could be a situation in which the case is denied for fraud, but the applicant is subsequently able to prove that they have been living overseas together for a long time, or there is a child born of the union.  I do note that we have seen situations in which the consulate or embassy was uncertain of whether there was actual marriage fraud and did allow a waiver to be done, which approval resolved the situation.  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.
