The United States was locked up by immigration for a month. Why hasn't it been lifted?

Does the subject want to ask, "Why didn't the United States let people go after being locked up by the Immigration Bureau for a month?" The reason for this is the following:

1. We haven't received the audit results from the Immigration Bureau.

2. The current epidemic situation is special, and non-immigrant visa holders are allowed to apply for extension of stay in the United States or change their status.

3. Get into financial trouble.
