I have H1B but my parents are US citizens, how do I get green card?

Employment-based applications and family-based applications both provide pathways by which a beneficiary may adjust status to become a Lawful Permanent Resident (to get a "Green Card"). Both processes are governed by extensive regulations and contain many eligibility requirements. It would be necessary to learn many more details about you, your employer and your employment in order to complete a worthwhile analysis and to advise about the pathway that would be the easiest, fastest and most likely to be successful. 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.
