Family immigrant visa rate

Frankly speaking, your situation is quite difficult. Generally speaking, the pass rate of this visa is certainly not as high as expected. I'm sure I suspect you have an immigrant tendency. I suggest you ask your sister to open the invitation. First, after all, your sister is an American citizen, and you seldom meet each other. There are natural reasons for applying for visiting relatives. Second, although your parents have green cards, they have no immigrants after all. If you ask them to open an invitation letter, I don't think the reason is sufficient, because I infer that you don't meet each other all the year round. In other words, because I often don't see my sister, it is more reliable to say that I go to see my sister. Materials should be prepared with sufficient travel plans, how to work, and strong binding proof (real estate, domestic kinship, etc.). ). It is not recommended to invite both parents and sisters.

Under normal circumstances, the last refusal will not affect your next visa. As long as you have sufficient materials and reasonable reasons. If you are simply visiting relatives, you can definitely only apply for a non-immigrant visa. I still suggest you let your sister drive. Try not to be inclined to immigrate.
