Can my step mother petition me to adjust my status without me getting affected by what my father did?

The situation with your father will likely affect the adjudication of your stepmother's petition for you. The step relationship depends upon the bona fide nature of the marriage of your father to your stepmother. The US government would have to be certain of the bona fides of that relationship before granting you residence status based upon it.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.
