Once the I-526 application is approved, many applicants will elect to finalize their applications through the U.S. Embassy or Consulate in their home countries. This is done for purposes of ease so as not to displace any family members needlessly before their time.
The I-526 approval, issued by USCIS in California, is directed to the National Visa Center in New Hampshire. A file is then created denoting the city where the ultimate process will take place at the U.S. Embassy or Consulate in the home country of the applicant. The forms are then directed to the applicant, with a notice to the consul to open a matter in its embassy or consulate.
Once the appropriate documentation has been submitted by the investor to the National Visa Center, a notice is sent to the consulate or embassy to schedule the applicant for a final interview to ensure that he or she and all members of the family remain eligible. It is unfortunate when any member of the family does not qualify for residency due to personal reasons, and the remaining members of the family are eligible to depart without that family member.
NOTE that the spouse and minor children are entirely dependent on the principal investor to allow them to also become U.S. residents.
