Good day! I am a Philippine passport holder under my married name. My husband holds a US passport. We plan to visit Vietnam in Jan. 2010 for 2-3 days only. I know Filipinos are visa exempt for 21 days. What about my husband?I read in the Vietnam Tourism site that spouses of those exempt are also exempt from applying for Vietnam visa if we stay less than 21 days. Can you please clarify. Thank you!
