The Embassy uses an online scheduling system for the scheduling of K-1 (and K-2 and K-3) visa appointments.  When a fiancé(e) case arrives at the Embassy, the Embassy will send the petitioner instructions for the online scheduling of a date for the interview. It is important that the petitioner maintains and regularly checks the e-mail account provided on the I-129F petition, as the Embassy will send the scheduling instructions to that e-mail address.

Do not schedule an appointment for a K-1, K-2, or K-3 visa appointment unless the Embassy has sent you instructions for doing so. 

The following items are required for the K-1 visa interview for each applicant in the case (the principal applicant and any derivatives):

• Form DS-160: Fill out the online DS-160 visa application by following the instructions at https://ceac.state.gov/GenNIV/Default.aspx. Print and keep the DS-160 confirmation barcode page.
• GT Bank receipt for the $265-per-person visa fee.
• International Passport: Your passport must be valid for at least 6 months past your interview date.
• Affidavit of Support (including tax returns): Applicants must provide an Affidavit of Support (Form I-134, available at http://www.uscis.gov/sites/default/files/files/form/i-134.pdf (PDF), and an IRS Tax Transcript). If the petitioner’s income does not pass the poverty threshold, a joint sponsor must also submit an Affidavit of Support along with his or her most recent tax return.
• Medical Exam: Arrange for a medical examination by an approved panel physician. You are responsible for paying for the medical exam. The medical examination results will be valid for no more than six (6) months, and they must be valid in order for you to travel to the United States. It is recommended that you get the medical exam 2-3 weeks before your interview date. A medical exam is required for all applicants, regardless of age.
• Police Certificate: Applicants age 16 or older must submit a police certificate for ALL countries in which they have resided for six months or more since age 16, or for any country in which they have ever been arrested. If you have ever lived or studied in another country for more than six months, or if you have ever been arrested, you MUST obtain a current police report from that country.
• Passport Photos: showing the applicant’s full face, without eyeglasses, on a white background. The required size is typical for passports: 1½ inches by 1½ inches (5 cm x 5 cm). For more detailed information on photo requirements, please visit: https://travel.state.gov/content/passports/en/passports/photos/photos.html.
• Original Documents: Bring all original civil documents and a photocopy of each document.  If you do not bring a photocopy, the original documents may not be returned to you.  Civil documents include, but are not limited to:

                     Marriage certificates

                     Birth certificates

                     Divorce certificates

                     Adoption decrees

                     Death certificates

• Evidence of your relationship with your petitioner from throughout the timeline of your relationship and that demonstrates you have an ongoing relationship.  This may include, but is not limited to, photographs together from throughout your relationship and communication records, such as chat history (directly from the web site or app and not copied and pasted), phone records, and printed e-mail correspondence.  You know the history of your relationship and should be able to provide evidence demonstrating the history of the relationship.

• Evidence of the relationship between you and any derivative children your case, demonstrating the history of your parental relationship.
• Court and Immigration Records: If you have been convicted of a crime or other offense, in the United States or elsewhere, obtain a certified court record covering each offense. If you previously resided in the U.S., you are encouraged to bring evidence of your immigration status during your stay, and records of any previous U.S. visa extensions and deportations that would be relevant for review.

Feel free to collect these documents before scheduling an appointment.  However, do not schedule an appointment for a K-1, K-2, or K-3 visa appointment unless the Embassy has sent the petitioner specific instructions for doing so.  If you appear for your appointment and your physical file has not yet arrived at post, the officers will not be able to interview you, and this will almost certainly delay your case.
