Do I have to Be Physically Present In The U.S. For The Entire Period I Am Required To Reside In The U.S. to become a citizen through naturalization?
No, you have to be physically present in the U.S for half of the time you are required to reside in the U.S. If you are married to a U.S. citizen, you have to physically reside within the U.S. for eighteen months. If you are not married to a U.S. citizen physically presence of thirty months will be required.
