Trong form I-797 em không thấy số hồ sơ HCM. Họ viết như thế này: You should allow a minimum of 30 days for U.S Department of State processing before contacting the NVC. If you have not received any correspondence from the NVC within 30 days, you may contact the NVC by email at
NVCINQUIRY@state.gov. You will need to enter the USCIS receipt number from this approval notice in the subject line. In order to receive information about your petition, you will need to include in the body of the email your name and date of birth, and the Applicant's (beneficiary's) name and date of birth.
Vậy là em chờ thêm 1 tháng nữa phải không ạ?! Khi có thư mới thì em sẽ báo liền. Em cảm ơn PhuongChau!
