How does one apply for consular processing?

Hi Devin, consular processing only occurs after a immigrant or non-immigrant visa petition has been approved by the USCIS and sent the the U.S. Embassy or consulate for issuance of a visa. In some cases, a U.S. Citizen petition can file a petition for an immigrant visa for a family member directly at the U.S. Embassy or consulate if they have resided in the jurisdiction of the embassy or consulate for 6 months or more. These rules vary from post to post. Hope this helps.
