我媽媽今年80歲了，之前來過美國三次，每次都是住5個月按時回去。前年她突發腦梗，現在身體行動不便，說話不太清楚。她生病前拿到的10年B2簽證還在有效期，我現在是綠卡，請問，
1）我想回國把她接過來與我同住一段時間，是否可行？
-No problem. Ths kind of desease does not matter for entry into US. Check the website of the US Embassy in China to see whether there is any limitation or requirements on entry into US due to Covid 19.
2）如果可行，入關美國時我需要準備什麽額外的資料嗎？
-You had better bring the doctor or hospital diagnosis to prove that your mom has cerebral infarction. This desease makes her unable to answer the questions clearly asked by the immigrant official when she enters US.
