Am I able to fix my father’s papers if I am 22 years old, currently working and going to school and how can I start?

Generally a U.S. citizen age 21 or older may sponsor a parent who is in the U.S. in an adjustment of status application process in the "Immediate Relative" visa category. There are many details, however, beyond relationship and age that determine eligibility. It would be wise for you and your father to consult with an immigration attorney who, after learning all of the relevant information about your father and your family, would be able to advise about immigration eligibilities, options and strategies, and then could offer legal representation in the often complex application process. Some immigration law firms, including mine, offer legal services on a "flat fee" basis so that a client will know the total expense from the very beginning, and a few immigration law firms, including mine, offer an initial consultation free of charge.
