How to find a relationship and a back door for American visas

What the landlord said is too detailed. What kind is it? In Beijing, Shenyang, or Shanghai and Guangzhou? In fact, the visa is not as difficult as you think.

If you are going to school, you must have an invitation letter from the other school and so on. In short, remember three points, don't show immigration tendency, have property certificate and have learning ability.
