Guys,

We are travelling to Nepal on China Southern Airlines via JFK-Guangzhou- KTM route. I am Nepali passport holder with GC status and my aunty is US passport holder. We have 2 hours transit while going to Nepal and 6.5 hours while coming back to US. Do we need transit visa? Has any thing changed on transit visa recently because some one I know was not allowed to take flight 3 days back. She had travel document(no passport) issue by US government, valid visa of Nepal and she had same route on same airlines.
