To give you a clear picture, we will divide the US fiancé visa application process into five main steps:

Step 1 Submit Form I-129F to USCIS.

The first form that applicants must submit is an I-129F. The forms can be downloaded from the USCIS website at the following link.

Now let’s look at how to fill out this form we should understand the basics as follows.

In this form, the applicant is a beneficiary, be careful not to enter information alternately when filling in the form. You must ensure that you will enter correct information all parts of the form and in which parts should be filled up with the information of the petitioner or beneficiary.

Form I-129F page3

Once completed, submit the completed I-129F Petition Form, along with a copy of the Applicant and Petitioner’s personal documents, to the USCIS office in the United State.

United States Citizenship and Immigration Services, or USCIS, is the first petition screening agency.

After the petitioner submits the application to USCIS, they will normally receive a message or email with the Receipt Number used to check case status of the petition within 7-14 days after submitting the documents.

Aside from receiving a message or email, they will also receive a Form I-797C, Notice of Action, also known as a Receipt Notice, which will be sent to the petitioner’s postal address as stated in the claim within 30 days of submission.

In this first step, there will be a $535 petition fee.

This petition fee must be submitted only as a check or money order issued by a US financial institution or from a credit card and will take the time to consider the petition with an average of 4 – 6 months.

Approval Notice USCIS

After the I-129F petition is approved by the USCIS, the petitioner will receive a Form I-1797, Notice of Action, also known as an Approval Notice, to confirm that the USCIS has approved your petition.

And, your approved petition is being sent to the National Visa Center (NVC) so that the NVC will create the case then forward your case to the US Embassy in the country of residence of the applicant.

When the embassy received your case, the embassy will send a letter to the applicants by post. It is a detailed case number or case number to use in the visa application process in the following step.

Step 2 Submit an online application and request an appointment with the US Embassy in Thailand.

After receiving the Case Number, Applicants must complete the Nonimmigrant Visa Application Form DS-160 online.

The DS-160 online form can be accessed through this link.

It will be noticed that the fiancé visa uses the same online form as the nonimmigrant tourist visa.

After submitting the information in the DS-160 you will need to pay the fiancé visa fee of 8,215 baht [information on April 10, 2020]

This notification will be sent to the email which the applicant provided when registering the system. Do not book an appointment even the system allow you to click any available date shown on the system until you gets the notification from the embassy. If you do so, the embassy will cancel your appointment booking and you have to pay the visa fee again if the embassy canceled your booking twice. So please be patient and wait for your turn.

Step 3 Health check

After your interview date is confirmed by the embassy

Applicants must make an appointment with the hospital that is accredited by the embassy at least 1 week before the scheduled interview appointment with the Embassy. Then that they can perform a medical examination for the purpose of using in visa applications such as Bumrungrad International Hospital, BNH Hospital.

Because the embassy will not allow applicants to be interviewed without the medical examination results to show to the staff.

The health examination results will be valid for only 6 months.

  • Case number letter and confirmed email, interview appointment date
  • 4 photos of the same size as the holder for a US visa

In which the official will determine whether the petitioner’s income is qualified to certify the fiancé by filling in the income information in this form.

To check whether the two of you actually know each other or are you really a couple? what’s your real purpose in applying for the visa? Along with viewing the relationship documents you have submitted.

You may also be interviewing about any job history you have taken including your overseas travel history. The staff will be interview you in English at the communication level.

The reason why the interview will be in English Language is because if you can interact with your fiancé in English then the interview should not be too difficult for you. However, if you are too nervous to speak English you can inform the staff for an interview in Thai as well.

If you are granted a visa, the staff will keep your passport. After that, they will send your passport attached to the visa page along with a package of documents that you will need to carry on the date of your entry into the United States.
