Visa Requirements

Foreign citizens may need to obtain a visa to enter the United States and attend the conference. For the most up-to-date information on whether you need a visa to attend MICRO 2019, check the U.S. State Department website.

Note that your country may participate in the Visa Waiver Program, in which case you may be able to attend the conference without a visa. If you have any questions or doubts, contact your local U.S. embassy/consulate.

If you require a visa, you should apply as soon as possible. Visa processing can take several weeks, and may require you to go in person to your local U.S. embassy/consulate.
