Visa/Travel Information

If you are in the U.S. on a temporary non-immigrant visa and plan to visit Mexico from San Diego, you should consult your country’s embassy in Mexico to determine eligibility.  Upon return to the U.S., you will need to present your valid passport (with at least six months before expiration) and your U.S. visa at the U.S./Mexico border. Please take note of whether your U.S. visa has been issued for a single entry or for multiple entries. If you have not been granted a multi-entry U.S. visa, you will not be able to return to the U.S. once you have entered Mexico. Your visa type may be determined by looking for the number or letter under the "Entries" section on your U.S. visa. Single entry visas are denoted by the number 1, whereas multiple entry visas are denoted with a certain number (2, 3, etc.) or "M" for multiple/unlimited entries. For more information, please visit the U.S. Department of State website about Visa Expirations.

International Division White Paper
In order to explore how best to facilitate interaction with international chemists, a working group was established between two governance committees: DAC (Divisional Activities Committee) as a representative to and liaison with the Technical Divisions, which are the home to the thought leaders in the various chemical disciplines; and IAC (International Activities Committees) as the representative for international members, which has the logistical and cultural expertise to facilitate interaction. The working group produced a White Paper that details the benefits, best practices and recommendations for international engagement.
