If you don’t show up to your immigration appointment with the court, you run the risk of being deported. This is what is called an Order of Removal in Absentia. If for some reason you didn’t make it to your appointment, you have 180 days to request the reopening of your case. If you didn’t receive a notification to go to court, and you didn’t show up, you could possibly request your case to be reopened even if it’s been more than 180 days. Requesting a new case in the absence of a notification of court is something that must be consulted with your immigration attorney.
