1）我一個親戚S，S的外婆和我的外公是兄妹，那S想來美國玩幾個月的話，可以算探親嗎？
-Fine.
還是說這種情況隻能簽旅遊簽證？
-The same visa type (B2 visa) for 探親 or 旅遊. Just use "探親和 旅遊" as the reason for the visa application.
2）如果算探親，那我需要提供什麽樣的證明材料呢？
-It is somewhat complicated in your case to prove your relative relationship with S, and you may figure it out by yourself. If you can not get the documents to prove the relationship, it does not hurt the B2 visa application that much and S may just explain it to the visa officer. The critical thing is that S has to prove his/her has no immigration intent by showing his/her connection to China tightly.
You may need to provide a invitation letter, your status proof such as H1 approval notcie/I-94, or green card, etc. and provide the I-134, financial support for travel expenses.
3）如果簽旅遊簽證，是不是隻能跟團，
還是說可以自己直接簽個人的旅遊簽證？
-Fine.
先謝謝了
