Once have biometrics appointment and assuming there are no issues can you leave the country i already have a alien registration card just renewing it?

Yes, if you have already completed your biometrics appointment and there are no issues with your application, you can generally leave the country. However, it's important to ensure that your current status allows for re-entry and that you have the necessary documentation to return. Additionally, check if your travel plans might affect your application process or any pending decisions. It's advisable to consult an Immigration attorney for personalized guidance.
