Does not being able to sign on the selective service affect my citizenship requirements?

In connection with an application to become a naturalized U.S. citizen, the USCIS may consider failure to timely register for the Selective Service to show a failure to obey the law or a failure to be attached to the U.S. form of government, but those considerations may be rebutted by an explanation, if accurate, that you were unaware of the requirements; that when you became aware of them you sought to register; that you had become too old to be permitted to register; and that in all respects you are law-abiding, you are attached to the U.S. form of government and that if the law were to so require you would be willing to serve in the military. It would be wise to engage an immigration attorney to represent you in the naturalization process and especially to address the failure to timely register with the Selective Service. Some immigration law firms, including mine, offer legal services on a "flat fee" basis so that a client will know the total expense from the very beginning, and a few immigration law firms, including mine, offer an initial consultation free of charge.
