If you are from a country other than the United States, you will need a valid passport or visa to attend the meeting. Plan accordingly, visas can take up to three months to obtain. The U.S. government is working to expedite visa processing; however, we encourage you to plan ahead to avoid any delays. Note: U.S. legislation requires foreign nationals to provide to air carriers a valid U.S. address during their stay prior to departure of their U.S.-bound flight. Most airlines require a passport number, as well as a valid U.S. address for the passenger’s stay, at the time of booking. The APS-CPS Joint Meeting is registered with the U.S. Department of State.
