1. Visit U.S Embassy or Consulate Website
The first, and perhaps most important step, in the Consular processing phase is to locate and visit the website of the U.S. Embassy or Consular office which will process your petition. The name of the U.S. Embassy or Consulate which will process your petition is listed on the letter you received from the NVC. Nearly all of the Embassies and Consular posts have websites now and most of them provide very thorough information about the specific procedures for processing K1 visas at their post.
To find the website for the Embassy or Consulate where your petition will be processed go to:
This website lists all the U.S. Embassy and Consular posts. Find the link to the appropriate Embassy or Consular post and visit the website.
Find the section called “Visas to the U.S.” or something similar. Once in this section look for the section that provides information on K1 visa processing. It will likely be under the "Immigrant Visa" section. Carefully review and follow the instructions on the website.
Each U.S. Embassy or Consular post has specific and unique procedures for processing the fiance visa. Many of the Embassy and Consular websites provide detailed instructions for that posts procedures. Try to locate these and review them carefully. In some cases, you will even be able to download the forms that your fiance will be required to submit, although this is not necessary because they will be mailed to your fiance directly when they are ready to process the case. Here is a link to the fiance visa instructions for the U.S. Embassy in Santo Domingo, Dominican Republic: http://www.usemb.gov.do/Consular/K1-K2-appointment-package-e.htm. This should give you an idea of what to look for on the U.S. Embassy or Consular website of the office that will process your case. *Do not follow these instructions unless your case is being processed by this post. This is only an example for illustration purposes only.
The site should also include an email address and phone number for contacting the Embassy or Consular post about the status of your case. VisaAmigo.com recommends that you limit your correspondence with the Embassy or Consulate to urgent matters as multiple, non-urgent requests will likely only delay the process further.
