My girlfriend immigrated to America. Now that she is a permanent resident, how should I go? What's the quickest way? It is best to have expert help.

1. Applying for your immigration by unmarried means is the fastest way, which takes about 6-9 months, but the probability of rejection in this case is also high;

2. After marriage, the husband and wife are reunited and immigrated, and the time is about 18-24 months.

Both of the above immigration methods need to prepare sufficient materials, including photos of you two, phone cards, air tickets for all tours and so on. This is all evidence that you are not a fake marriage immigration.
