Dear Sir/Madame,

I am Thai citizen, but I am currently studying in US. I have Chinese single entry visa now and I will travel from US to Beijing on 25 March and will go back to US on 12 April. However, I change my plan. I will go to Beijing on 25 March. Then, I will fly from china to Bangkok to visit my family on 3 April and then fly back to Beijing on 9 April and catch the flight from Beijing back to US on 12 April.
Anyway, I wonder do I need to reapply for double entry Visa in US? Is it possible for me to apply Chinese Visa again in Bangkok after I left Beijing?
