父母有綠卡,短期回國時,由於突發疾病,治療調養,在國內待了三年,現在想來美定居,是申請SB-1好,還是直接作廢,申請B1來美後,再重新申請綠卡,謝謝各位老師
-Your parents have to have strong evidences to support the SB-1 visa application because this visa is very strict to be issued. So, it is hard for me to give you a suggestion without knowing details. If the SB-1 visa application fails, their green card will be taken away by the Consulate during the visa interview, thus it might hurt their B1/B2 visa application.
