if my married sister is in the US (LEGALLY) how long will it take if I A US CITIZEN SPOUSE HER?

Even if your married sister is in the U. S. legally, it will generally take the same amount of time for her to obtain permanent residence inside or outside the country. Currently for the month of June 2019, those siblings who filed I-130 petitions before 12/1/06 are eligible for their final immigration, so the waiting time is now about 12 years. Whether inside or outside the United States, the final action date on the visa chart must be current before a person can be adjusted to permanent residence in the U. S. or given an immigrant visa at the home consulate or embassy.
