TWOV for departure AND RETURN flights?
Hello I am traveling from Los Angeles California to Ho Chi Minh City with a 10-hour layover in Xiamen. My return travel is the opposite route with an 8-hour layover. Can I acquire a 24-hour travel with out visa for this?
Will I need to acuire a new TWOV when I return to the USA 7 days later? I would like to depart the airport on the first leg of the travel to explore Gulangyu Isle with a 24-hour vise-free entry. Is this possible? For the return travel with only an 8-hour layover in Xiamen may I also explore Xiamen outside of the airport with a 24-hour vise-free entry? My original one will no longer be valid, correct?And what is good to see in such a short time? What will be my costs? Thank you so much for answering do many questions 😃
