The length of time K3 visas take to process varies, and each is processed on a case by case basis. Applicants who take care to provide complete information tend to see their applications go through first.
Occasionally, an application requires further administrative processing, which can hold up the approval process, but those people whose applications require further processing are made aware of the delay at the time of their interview. Extra processing is usually completed within 60 days.
Each K3 visa is processed by the U.S. Consulate or Embassy. Applicants need to provide accurate information, go through an interview and if approved, receive a sealed packet with the documents necessary. Applicants need to avoid opening this packet as it is for a DHS immigration official to open when the applicant enters the country.
