My sister is a us citizen can she petition for me i am living in the us been here since how long will it take to get a green card

Your sister can apply for you while you are here in the States, but her petition does not give you any rights to stay in the country while your case for immigration is pending. For the month of October 2021, the F-4 category for sponsored siblings of US citizens is available for immigration visas for those who filed before March 22, 2007 for all countries of the world except for India, Mexico, and Philippines natives who must wait longer. If born in all other countries, the waiting time is thus 14 years currently.
