Visitors Eligible for Visa Waiver Program
You may be eligible to visit the US without an immigrant visa if you are traveling for tourism or business, for up to 90 days, with a passport issued by one of the countries that participate in the Visa Waiver Program (VWP).
Please refer to the above VWP link for the procedure and necessary document when traveling to US.
If you are traveling to the United States with a passport issued by any other country, you must apply for a visa. Please read these procedures carefully:
To apply for a visa, you must have a “letter of invitation.” Cluster will issue letters of invitation to assist the process. Be sure that you have registered *and paid in full*. Then, send your request to firstname.lastname@example.org with title “Request Visa Letter of Invitation for First Last”, and provide the following information:
- Full name
- Legal address
- Place/date of birth
- Source of funding
- Name/email of contact at Embassy (if available)
Once we have received this information, we can send a PDF signed letter confirming your registration.
After you receive the letter of invitation, visit your local United States embassy webpage or call consulate for the visa application procedure. For information on the embassy or consulate closest to you, see Links to United States Embassies and Consulates Worldwide. We strongly recommend that you start the process as soon as possible in order to obtain the necessary documents.
Note that when you go to the embassy or consulate for your interview, you will be asked to pay a nonrefundable application fee and submit necessary materials. Detailed information can be found in the US Embassy webpage in your county.
