If your application for a Green Card renewal gets denied, you will receive a letter which will explain the reason behind your denial.
Generally, a negative decision cannot be appealed; you must file a motion to “reopen” the case or “reconsider” the case. The motion needs to be submitted at the office which made the negative decision. You should contact an experienced immigration lawyer for assistance to ensure your Motion is properly researched, written and filed.
A qualified and experienced immigration attorney can provide an effective resolution to Green Card denials.
