IMPORTANT NOTICE:  Passports are now required for ALL air travel outside of the USA.  Cruises outside of the USA without air travel may still honor a government issued picture ID and stamped, certified birth certificate at this time, only if boarding a round trip cruise from one U.S. port.  APPLY NOW for a passport and be ready for the new land and sea travel requirements that started in June 2009!  Black Diamond Travel recommends that ALL travelers obtain and use passports for all their travel plans.

As of this time, passport processing time is estimated by the U.S. State Department website as within four weeks of receipt for routine applications, and for expedited service within about two weeks.  Check with us for current estimates of processing time.  If you are planning any foreign travel, we recommend you apply for your passports (or renew if expiration is less than six months from planned return to USA) NOW.  Don't miss your trip due to lack of a valid passport!
