Hello,
My US entry permit was expired and now I do not have a valid US entry permit on my passport.I am going to india for my US entry permit extamping from the USA.
I have booked my China Sourthern`s flight and I`ll stay for 2 hours in Guangzhou.So my concern is that
Do I need to get transit G type?
Can I travel to India without Valid US entry permit?
Your earliest response would be highly appreciated and I look forward
