我在網上看有人講放棄綠卡可以得到一個十年的簽證，但也看到了有人放棄綠卡，結果被拒簽B2 （印度人）.
-Not ten year B2 visa, but normal one. Normally she should have no problem to get the B2 visa after giving up the green card. I have known several people get the B2 visa after they gave up green card and never heard someone did not get the B2 visa yet.
申請放棄綠卡並申請B2，她要到哪裏去辦理？她住在大連。
-She can just go to the US Consulate in Shenyang, Beijing or other where in China to abandon the green card and apply for the B2 visa there at the same time or any time later.
Here is the website of US Consulate in Shanghai for abandonment of green card fro your information (you can find similar information from other US Consulates):

如果去廣州申請SB1，要去兩次，她覺得身體上太不方便了，怕吃不消。
-She can stay in Guangzhou for several days (one trip) to complete the whole procedure (normally two interviews for SB-1 visa plus immigration visa are taken in a few days).
她很希望在美國住在美國，甚至在美國買好了墓地。她過去幾年沒有file過任何稅，不知道這是否影響她的申請SB1簽證。
