If you are a non-U.S. visa holder, you may need a visa to enter the United States. If you already have a U.S. visa, please check the expiration date to make sure your visa will not expire before or during your planned travel dates.
The following website can help determine whether or not a visa is required:
U.S. Department of State - http://travel.state.gov/visa/visa_1750.html
If you should require a visa, contact the U.S. Embassy Consular Section in your country to determine visa processing times, or visit the “Visa Wait Times for Interview Appointment” page of the U.S. Department of State website (http://travel.state.gov/visa/temp/wait/wait_4638.html)
Advance travel planning and early visa application are important, since visa applications are subject to a greater degree of scrutiny than they have been in the past. To assist in your visa request, you may request a letter of invitation to attend HELI-EXPO 2012. Please complete the “letter of invitation” form. A letter of invitation does NOT guarantee the issuance of a visa. The decision to issue a visa is the sole judgment of the local U.S. Embassy or Consulate. HAI is unable to assist with the actual visa processing. HAI cannot provide any financial support for travel, registration fees, or local expenses
To request a letter invitation please complete the form below. Please note: your letter will be sent by email within one week.
