Recently, I attempted to fly with China Eastern Airlines after purchasing a round-trip ticket for ONLY 3 days with Trip.com online. I was coming close to completing a 90-day visa in Japan as a United States citizen. The flight departure was on the weekend, Saturday to be exact, and the main immigration branch known as "Office Relocation Notice of Fukuoka Regional Immigration Bureau" in Fukuoka was closed, with only days before the 90-day visa expired.
The flight was from (FUK) airport in Fukuoka Japan, heading to (PKX) airport, Beijing Daxing International Airport, with a transfer in (PVG) Shanghai Pudong International Airport. The China Eastern ticket counter agents would not print a boarding pass without a China visa, and printed a couple of documents, one of which stated "NO HOLD CHINA VISA".
I was only visiting the largest international airport in China to write Google Reviews for hotels, spas, restaurants and shopping stores. This caused a stay in Japan until the last day of the 90-day tourist visa.
The first day the Main Immigration Office was opened in Fukuoka was that Monday after the weekend. I visited and explained the current situation to the immigration staff members with a translator present, in Fukuoka Airport. They assisted by completing an application for a 15-day extension, costing 4,000 yen, cash only. I paid the Ministry of Justice - Government of Japan - Certificate for Payment of Fee (Revenue Stamp). This process took most of the working day, from 9:00 am to 4:00 pm before receiving a 15-day extension stamp visa on my United States of America passport.
On some of the documents provided by China Eastern staff, it shows there are "exemptions" for nationals of the USA with a normal passport, and stay of maximum 30 days. With an onward flight, with confirmed onward air, cruise or train ticket to a third country within 144 hours from the day of entry, one can get a TWOV. Another document states that the TWOV facility does NOT apply when passengers arrive on a direct flight from the USA.
Are United States citizens required to have a China visa to visit only an international airport in China, which has its own hotel service, under the 144-hour limit provided in a document by China Eastern?
