Invitation Letter
International attendees often need a letter of invitation in order to obtain a visa to visit the US . Because of increased scrutiny of visa applicants, many potential attendees of scientific meetings in the United States have experienced unusual delays in obtaining travel visas.

If you need a letter of invitation and have not yet requested it, please contact Natasha Charles (ncharles@seas.upenn.edu) and she will forward it as soon as possible. In order to compose and send your letter, she will need your document number, email address, and your complete mailing address.
