If this was after you had committed 3+ misdemeanors that involved drugs, crimes against persons, or any combination, or a felony, it is 10 years. If, after an aggravated felony(careful, the list of what is considered an Aggravated Felony is growing), then it is 20 years. Regardless of the severity of the offenses we can help you in all aspects of immigration law including immigration waivers and immigration appeals. In addition, you cannot be charged under this section (8USC § 1326) unless you were physically deported. But, they can actually get you for making an entry past the 12-mile limit! If you are just trying to make an attempt in front of an officer, then that is different.
