Which agency is the best for Hangzhou to immigrate to the United States?

It may not be the most professional answer, but this is my personal experience. The year before last, relatives wanted to immigrate to the United States and ran many intermediary companies in Hangzhou. In the end, they chose overseas Chinese immigrants from Zhejiang. They got their green cards by investing in immigration at the end of last year, but there are so many troubles in the intermediate procedures such as immigration.

Are you satisfied with the above answers?
