我太太两年前回国探亲，一次例行体检查出癌症。经过了一系列治疗（最后一次化疗在去年初结束）。但身体虚弱不适合长途旅行。现在觉得恢复好了准备返美。听说这种情况下用绿卡入境，移民官要么没收绿卡原机遣返。要么扣留绿卡，让人入境等待移民官裁决绿卡持有人居住美国的意愿再决定绿卡的有效与否。
-Porbably yes, but either one of the two outcomes is not good in your wife's case.
请问我太太再入境时能选择后者吗？
-Because your wife's serious illness is the factor to provent her from returning to US on time, she is qualifed for application for SB-1 visa in the US Consulate in Guanzhou to come back to US. SB-1 visa allows her to reinstate her green card. This is the best way for her and I suggest her to apply for SB-1 visa by providing the evidence of her illness and treatment such as hospital bills, diagnosis, Dr.'s verification letter.

这两年我一直保有在美国的工作。
