Important Notice:
Technical specialists are continuing to work on the Department of State's consular systems. While most applicants are now able to access this site, those who are still having difficulty should wait at least 24 hours before trying again and visit http://nvc.state.gov/solutions for instructions. We expect there could be heavy traffic on CEAC over the next several days as applicants attempt to submit their forms and pay their fees online. Thank you for your patience as the Department continues to resolve recent technical problems with our consular systems.
