TA在國內進行了cancer related 的手術治療。醫生建議再進行1～2年的中醫調理。再說， TA在美國連白卡也沒有，治療條件比在國內差多了。 這個理由strong嗎？
-I thnk so, provide the Dr. dianogsis/letters indicating the illeness do not allow him to travel long distance and need to be continue treatment in the hospital an also provide the hospital bills to show the entire treatment history. After he get the SB-1 visa to enter US, his green card will be activated.
So,TA要去廣州申請SB-1 Visa，如果不過的話， 就直接把綠卡交上去，改簽B2？
-No. Need to make another appoinment for B2 and green card abandoment.
Just one trip， right？ 我們這裏需要為B2準備什麽材料嗎？
- One trip for green card abandonment and B2 visa applicaiton. Complete I-407 for abandonment of green card, and complete DS-160 online for B2 visa application. Check the US Consulate embassy website for the B2 visa applicaiton and green card abandonment. He can apply for the SB-1 visa or B2 visa in any one of the US Consulates in China whichever is convenient to him.
有朋友說， 可以參加中國去加拿大的旅行團，然後我們去溫哥華接TA， 再開車從西雅圖進來。 可行嗎？ 風險如果？
-Don't do that.
謝謝！
