Many parents whose children are studying in the U.S. often want to explore a new environment, visit, share important milestones with their children such as graduation ceremonies, or simply encourage their children in the early days away from home. Owning a US tourist visa (B1/B2) is the "passport" that parents must have to set foot in this country. In this article, IDP will learn with parents the conditions for applying for a US tourist visa, the documents to be prepared, the cost, as well as useful interview experiences to be more confident in the application process and improve the success rate.
1. Overview of US Tourist Visa
1.1. What is a US tourist visa?
The U.S. tourist visa, also known as the B1/B2 visa, is a short-term visa for foreign nationals who wish to enter the U.S. for non-settlement purposes. This is the most popular type of visa for those who want to come to the U.S. for a short time, including parents visiting their children to study abroad.
B1 visa: For those who come to the U.S. for short-term business purposes, attend scientific conferences or seminars, educate, sign contracts, or participate in professional events.
B2 visa: For tourism purposes, visiting relatives (e.g., parents visiting their children studying in the U.S.), medical treatment, or participating in social activities, cultural exchanges.
B-1/B-2 visas: A combination of both purposes – work and travel in the same trip.
1.2. How long is a US tourist visa valid for?
Usually, U.S. tourist visas (B1/B2) are issued for up to 12 months, allowing the holder to enter the country multiple times during this period. This is especially convenient for parents because they can visit their children in the United States many times a year, without reapplying for a visa.
So, how long can a US tourist visa stay? Basically, the maximum length of stay per entry is not fixed. Upon arrival at the U.S. border crossing, Customs and Border Protection (CBP) officers will decide and stamp the number of days you are allowed to stay. Normally, visitors, including parents, are allowed to stay for up to 6 months, which is enough for parents to visit, attend graduation ceremonies or take care of their children for a short time.

2. Conditions for applying for a US tourist visa
When applying for a B-1/B-2 visa, parents need to prove to the Consulate that their trip is short-term only. Under the U.S. Citizenship and Immigration Act, all B-1/B-2 visa applications are considered to be intended for long-term residency by default. So, you must provide evidence to prove the opposite, including:
Clear purpose of the trip:
The applicant should clearly state what the purpose of his or her application for the US B1/B2 visa is, and provide a specific length of stay. In the case of parents, the purpose is usually to visit their children who are studying in the US or to stay for a certain period of time. The declaration of specific and clear purposes will help increase the reliability of the dossier.
Solid financial ability:
Parents need to prove that they have enough finances to pay for the entire trip (airfare, accommodation, living expenses in the US)
Proof of commitment in Vietnam:
This is a key factor to prove to the Consulate that the parent will return after the end of the trip. Parents can prove through stable employment, family, property, or social/economic constraints in Vietnam to ensure you will return from your trip.
3. What documents are required for a US tourist visa application?
When applying for a visa, you will need to pay the prescribed fee and prepare the following basic documents:
Electronic Nonimmigrant Visa Application Form (DS-160).
Parents need to complete the application form and submit it online before scheduling an interview at the U.S. Embassy or Consulate.
The passport must be valid for at least 6 months
after the expected date of departure from the US (except for special cases agreed between the US and some countries). If there are dependents in the passport, each person who wants to apply for a visa must apply for a visa.
The 2 x 2-inch (51 x 51 mm) card photo was
taken within the last 6 months, complying with the standards for size and content. In the case of visa extension, the newly submitted photo must be different from the photo used in the old visa.
If the visa is approved, some cases may require an additional
visa issuance fee
(called a reciprocal fee), depending on the applicant's nationality. And if parents are required to pay before the interview, they will also need to provide a receipt of payment of the application fee.
3.1. Supporting documents during the visa interview
During the interview, the consular officer will review the application based on various factors such as work, family situation, study or travel plans, and ties in Vietnam. Each dossier will be independently evaluated in compliance with the law. In addition to the basic documents, parents should additionally prepare:
An invitation/confirmation letter from the child or a confirmation of the child's study at a school in the United States to confirm the purpose of coming to the United States.
Transcripts and academic results of children at American schools
Financial proof documents: savings books, payrolls, labor contracts, assets.
Documents that are binding in Vietnam: employment contract, proof of family relationship, or bank account
3.2. Important notes in the process of preparing documents
Do not submit false documents or false information
If parents are concerned about confidentiality, bring the papers in a sealed envelope to the interview; The Embassy or Consulate will keep your information confidential.
Only bring documents directly to the interview, do not send any supporting documents by fax, email or post.
The visa approval is based on the constraints of parents in Vietnam (family, work, property, etc.), not guarantees from relatives in the US. An invitation letter or financial sponsorship letter is not required and is not a determining factor in whether a visa is approved or not.
4. Cost of applying for a US tourist visa
