請問8老師：我想給我媽申請移民。她人在國內， 我爸早年去世。 請問需要我媽準備那些資料？我媽快80了，一人住在老家。最近家裏有親人回去探親，想麻煩她一起幫我媽辦了。
-Because your mother's age is high, it is not convenient for her to apply for immigrant visa in China. So, she had better apply for B2 visa to enter US. Then, you can file I-130 and she can file I-485 90 days later after she enters US.
She needs to prepare the following certificates (公證書):
her birth certificate, her marriage certificate, your father's death certificate
If she had more than one marriage and divorce history, then she also needs to prepare the prior marriage certificate and divorce certificate.
You also need to prepare your personal birth certificate.
