How do I read and understand my visa

Please use the illustrated guide below to learn how to read your new nonimmigrant visa (for travel to the U.S. as a temporary visitor).

visa example

In addition, as soon as you receive it, check to make sure information printed on the visa is correct (see below). If any of the information on your visa does not match the information in your passport or is incorrect, please contact the nonimmigrant visa section at the embassy or consulate that issued your visa.


A visa must be valid at the time a traveler seeks admission to the United States, but the expiration date of the visa (validity period/length of time the visa can be used) has no relation to the length of time a temporary visitor may be authorized by the Department of Homeland Security to remain in the United States. Persons holding visas valid for multiple entries may make repeated trips to the United States, for travel for the same purpose, as long as the visa has not expired, and the traveler has done nothing to become ineligible to enter the United States, at port-of-entry.

General information about ESTA and travelling without a visa

ESTA is an automated system that determines the eligibility of visitors to travel to the United States under the Visa Waiver Program (VWP) administered by the Department of Homeland Security (DHS).

Please visit the official U.S. immigration website for more information about ESTA:


An approved travel authorization via ESTA only authorizes a traveler to board a carrier for travel to the United States under the VWP.  In the same way that a valid visa does not constitute a determination of admissibility, an approved travel authorization obtained via ESTA is not a guarantee of admissibility to the United States at a port of entry (POE).  U.S. Customs and Border Protection (CBP) officers make admissibility determinations at U.S. ports of entry or pre-clearance locations.

How will I get my passport and visa after the interview?

Applicants must bring a self-addressed envelope with a FollowMe label to the visa interview to allow return of their passport by mail. It is not possible to purchase envelopes, stamps or labels at the Embassy.

The best option is the prepaid padded envelope from the Post Luxembourg, size 162x229mm.

You must attach an online tracking label for FollowMe which allows you to track your passport. It can be purchased online at www.eservices.lu or at a local post office

Please make sure to write your name and address correctly on the envelope to avoid delays and misrouting, as explained here. If you use your employer’s address please put the name of the employer/company first, c/o your name. The address should be in Luxembourg. If you do not reside in Luxembourg you can have it sent to an office, friends or relatives in Luxembourg.

If you need your passport for other travel please inform staff when submitting your application. The passport can be returned to you after the interview and you may bring it back later for issuance of the visa.

I do not know how to answer a question on the DS-160. I made a mistake on the DS-160. Do I have to correct it?

If you’re unsure how to answer a question, please answer to the best of your ability. You can discuss and explain your answer on the day of your visa interview. If you made a minor mistake, such as biographical information or travel plans, you do not have to complete a new DS-160. Please let consular staff know that you made a mistake when you come for your visa interview at the Embassy.

What if I lose my internet connection, the application “times out,” or I receive an error? Will my application be lost?

Please take note of your application ID number and answers to the security questions when you start completing the DS-160 form. All information is automatically saved when each page is completed, so your application will not be lost. You will need to enter the application ID number and respond to security questions as prompted, to retrieve your application. Once your application has been retrieved, it will begin at the last page you completed. You will be able to edit previous pages, if needed.

I submitted my DS-160 online. What happens next?

Electronically submitting your DS-160 online application is only the first step in the visa application process. Once you have submitted your DS-160 online application, you must schedule an interview with a consular officer on the Embassy’s website. It is important that you plan ahead and check current visa appointment wait times. Please read all the steps in our section how to apply to make sure that you’re prepared for your interview with the consular officer. If you arrive without necessary documents, we may have to cancel your appointment.

I scheduled an appointment and cannot come, or wish to change the date of my appointment.

You can use your confirmation ID to reschedule your appointment on our website. If you do not have your confirmation ID, you will need to complete a new DS-160 before you can book a new slot. Please note that if you do not come for your appointment without rescheduling, your DS-160 will be cancelled and you will need to complete a new one if you decide to apply later.

Can I bring my mobile phone, tablet or laptop inside the Embassy?

You can bring your mobile phone and it will be kept at the entrance.  A laptop or tablet is not allowed, it will not be admitted to the Embassy and it cannot be stored at the entrance. Please leave your laptop or tablet at home or store it securely before you arrive. If you arrive with items you cannot bring into the Embassy we may have to cancel your appointment.

I do not speak English. Can I still have my visa interview?

Your interview will be held in either English, French or German. If you do not speak/understand one of these languages, please make sure to bring someone with you who can translate for you into one of these languages. Please note that this person should not be an immediate family member. You do not need to book an appointment for the translator, the person should have a valid ID.

How can I pay for my visa? Do I have to pay online before my interview?

The only way to pay the application processing fee in Luxembourg is on the date of your appointment in cash at the Embassy, before your interview with the consular Officer. You can only pay cash, in Euros or US$. We do not accept payment by V-PAY or credit card. If your visa application is denied, this fee is non-refundable.

For some nationalities and visa types an additional issuance fee must be paid before the visa can be issued. Detailed information is available in fees and reciprocity tables.

Applicants for F1, M1 and J1 visas must pay the application processing fee at the Embassy AND the SEVIS fee online BEFORE they come to the interview at the Embassy. It is not possible to pay the SEVIS fee at the Embassy.

How long will it take before my visa is issued? How will I know?

The consular officer will inform you at the interview if you are approved to receive a visa. If approved, you will receive your passport and visa in the mail within the next 5-7 business days. Collection of your passport at the Embassy can only be authorized by the consular officer depending on your circumstances.

In some cases the consular officer may advise you that additional processing is necessary to determine your eligibility for a visa. The consular officer will return your passport to you and may ask you to provide more documents. Most of these administrative processes are resolved within 60 days of the interview, but the time may vary depending on the individual circumstances of each case. Once final authorization is received, we will contact you to return the passport for visa issuance. You can track the status of your application at ceac.state.gov.

Can I use my visa for multiple trips to the U.S.? What if my visa expires before my departure from the U.S.?

A visa must only be valid at the time a traveler seeks admission to the United States, but the expiration date of the visa (length of time the visa can be used) has no relation to the length of time a temporary visitor may be authorized by the Department of Homeland Security to remain in the U.S. Persons holding visas valid for multiple entries (M) may make repeated trips to the U.S., for travel for the same purpose, as long as the visa has not expired, and the traveler has done nothing to become ineligible to enter the United States.

My passport expired but I still have a valid visa in this passport. Can I still use it for travel to the U.S.?

If your visa is still valid you can travel to the U.S. with your two passports, as long as the visa is valid, not damaged, and is the appropriate type of visa required for your principal purpose of travel. (Example: tourist visa, when your principal purpose of travel is tourism). Both passports (the valid and the expired one with the visa) should be from the same country and type (Example: both Uruguayan regular passports, both official passports, etc.). When you arrive at the U.S. port-of-entry (POE, generally an airport or land border) the Customs and Border Protection Immigration officer will check your visa in the old passport and if s/he decides to admit you into the United States they will stamp your new passport with an admission stamp along with the annotation “VIOPP” (visa in other passport). Do not try to remove the visa from your old passport and stick it into the new valid passport. If you do so, your visa will no longer be valid. When renewing your passport, it is important to ask the passport authorities of your country not to damage your visa by punching holes or cutting off part of the page as they cancel your old passport.

I changed my name. Can I still use my visa which was issued in my old name?

Travelers who have changed their name due to marriage, divorce, or because of any other circumstance may travel using their documentation showing different names as long as you also travel with proof of your legal name progression such as: a marriage certificate, a divorce decree or court documents showing a legal name change.
