I will be going to Hong Kong (3/25 - 3/28/10), Thailand (3/29 - 4/2/10, and Korea (4/5 - 4/11/10) of this year. I will be back in the US April 11, 2010. My passport expires November 23, 2010. Would I have any problem with my passport getting in those countries since it will expires this year? Please advise.
