Many immigrants are removed from the US each year for a wide variety of reasons. Under Immigration and Nationality Act (INA) section 212(a)(9)(A) and (C) make someone who has been removed from the US inadmissible into the country. However, such individuals can still in many cases apply to reenter the country. The exact steps to take to apply for readmission vary, but a first step is to file I-212 (Application for Permission to Reapply for Admission into the United States After Deportation or Removal), to petition for readmission into the US. You can only use this form to file for readmission if you are inadmissible under Immigration and Nationality Act (INA) section 212(a)(9)(A) and (C). If you are inadmissible under INA section 212(a)(9)(C), you must wait ten years before attempting readmission.
