restrictions for US Passport? I am planning a trip to Asia exploring different areas such as HK, Taiwan, Japan, Singapore, and Malaysia. Length of stay per state or Country is around 1-2 months. Can I be away from US for over 6 months? Any Visa requirements into any of these countries and is there any the Length of Stay restrictions? Can I work while I am exploring the city? What do I need to do to make this trip possible? Thank you for your help!
