Is it possible to get marry a green card holder if I am on B1/B2 visa ?

a person admitted as a visitor may marry a green card holder. the person marrying a green card holder does not have the right to remain in the US by that marriage or the filing of the I-130. It is 18 months before the sponsored spouse may file for a green card. during which time the sponsored spouse must be in legal status or outside the US.

There are several responses to your question that require answers from you before committing myself to resolve your question. First, if your spouse- to -be is a permanent resident, depending on your country of origin, you will have to be on a waiting list called a Priority Date that moves up or down every month. As a tourist you cannot travel into and out of the country as an intending immigrant because of a policy called "preconceived intent." A tourist visa is not a dual intent visa. How much longer before your fiance is eligible for naturalization? These questions require an interview with an experienced immigration attorney.

You may not be eligible for entry as a non immigrant with an immigrant intent.
