A motion to reopen a case can be filed if you have new facts or evidence that were not available at the time of the initial decision, or if new legal grounds have emerged. Common reasons for filing a motion to reopen include:
Changes in the law that could affect your case
Newly-discovered evidence that was unavailable during the initial proceedings
Clerical errors or mistakes made by USCIS in the original decision
Remember that timing is crucial when filing a motion to reopen, as there may be strict deadlines based on the specific situation.
