Can I fix my dad’s papers even though I don't work and he’s providing for me and my kids?

Significantly more information is needed about you and your father in order to assess immigration eligibilities, options and strategies. Are you a U.S. citizen? Are you age 21 or older? Is your father in the U.S.? If so, what are the details about his entry into the U.S., such as date, visa, etc.? It would be wise for you and your father to consult with an immigration attorney who, after learning all of the relevant information could advise about immigration eligibilities, options and strategies, and could then offer legal representation for the often quite complex application process.
