Apply for your travel visa for entry into the United States as soon as possible. Entry requirements into the United States have tightened considerably, so if you will require a letter of invitation in order to attend this conference, please notify us as soon as possible. This will allow adequate time to obtain your visa.
If you need a letter of invitation to attend the IATUL 2010 Conference we will send you a signed letter in an e-mail attachment that you can provide to the nearest US consulate or embassy in your country (http://www.usembassy.gov/). Purdue University will not contact consulates, embassies or the State Department on your behalf.
