Do I have to file I-130 form and I-485 for my mother if currently she is here in the USA?

For a foreign national who is present in the U.S. (after entering lawfully and with inspection), and who is the parent of a U.S. citizen age 21 or older, to become a Lawful Permanent Resident (to get a "Green Card"), the U.S. citizen child must file a Form I-130 Petition for Relative Alien and the foreign national must file a Form I-485 Application for Adjustment of Status. Of course, there are other forms and supporting documents necessary for the application process, and there are many other details that also determine eligibility. It would be wise for you and your mother to consult with an immigration attorney who, after learning all of the relevant information, could advise about eligibilities, options and strategies to attain your goals, and who then could offer legal representation in the often complex application process.
