China CITIC Bank only gave one copy of the second US visa fee receipt, and the Internet said that it needed two copies. What happened?

I think the bank gave you two. One is yellow and the other is white. The first copy was taken away by the embassy, and the second copy was returned to you after being stamped and signed. Receipt security check.

Note: 3. To apply for a non-immigrant visa, you need to pay an application fee of 966 yuan at the designated branch of CITIC Industrial Bank (the application fee will not be refunded whether the visa is approved or not). During the interview, two application fee receipts must be issued.

The visa application fee receipt is non-loss-reporting and non-refundable, valid for one year, and can be purchased by CITIC without identity documents (4.7 CITIC Dongmen Verification).
