We have some friends in China who we would like to come to our wedding next year. We have been friends for about 6 years, have attended their weddings in China, have an ongoing friendship with their entire family, etc.
They need a visa to travel to the US and from this website
, it looks like they need proof of funds to cover expenses while in the US. They do not have these funds. These people are not wealthy and we would be helping them with the cost of plane tickets and providing a place for them to stay while they're in the US. They have no intention to stay in the US: English is non-existent; they have very young children that will remain in China; they have small retail businesses in their hometown that they run themselves; they care for their parents and grandparents who will remain in China. We just want them to visit for about a week to attend our wedding and meet our families. Also, they're Muslim, which I imagine could cause some issues (though they are the Hui minority, which does not have the same history of issues with either the Chinese or American governments as the Uighurs do, for instance; see this article
These people are basically like family to us, and we have pictures of us with them and their family going back 6 years.
Is there any possibility of them getting a US visa? What can/should we do to help?
