Question about traveling into China, then to Japan, back to China and finally, home to the US
Hello! I have posed this question to our embassy and have yet to get an answer so I am hoping you can assist. I have read about the 240-hour visa-free policy but I am unsure how it may apply to my situation.
We are looking at a tour that will have us fly into Shanghai on day 1 and depart for a cruise to Japan on day 2. On day 15 we would return to Shanghai from the cruise and would be spending 4 days in Shanghai before flying back to the US. My concern is that although we will only be spending 6 days total in China overall, our total trip would have us still being in and returning from China on our 15th day following our initial arrival.
I wanted to try and determine if a Visa would be necessary for this travel, or if departing then re-entering China during our visit constituted an acceptable use of the 10-day visa-free policy.
Thank you in advance for your help!
