Did you know that the United States Citizenship and Immigration Services (USCIS) can deny your N-400 Application to become a U.S. Citizen if you are a male that failed to register for the Selective Service between your 18th birthday and your 26th birthday? Many of our clients had no idea about their obligation to register with the selective service. Find out if you are required to register here. If you are a male between 18 and 26 and you are required to register, you may do so online at www.sss.gov. If you are a male that was required to register, but didn’t, and you are 26 or older, consult with an immigration attorney before you apply for citizenship.
