Question: My passport is swiss and I am living at Vancouver (with a student Visa valid until 2018) and I have a valid ESTA (until July 2016). Around July 15, I'll be crossing the border (between Vancouver and Seattle) to hitchhike in the USA along the west coast for about 2 weeks or 1 month.

At the moment I'll pass the border, I won't be able to indicate where I'll spend my first night. I won't be able to accurately say how much time I'll spend in the USA. Is it an issue?


Answer: Entering USA as a tourist without any plan


Question: I have a 75 hour trip to Beijing (PEK) coming up in October. I shall enter at PEK on a flight from London, arriving at 0930 and continue onwards by air to Hong Kong three days later at 1230, and I shall be travelling on an ordinary British passport.

I understand that the 72 hour transit visa on arrival actually begins the midnight after my arrival (and not immediately after arrival). The relevant text from TIMATIC is
Visa required, except for Holders of British passports
endorsed  British Citizen  holding confirmed onward airline
tickets to a third country, if arriving in and departing from
the same city:
- at Beijing (PEK), Chengdu (CTU), Chongqing (CKG), Dalian
(DLC), Guangzhou (CAN), Hangzhou (HGH), Shanghai Hongqiao
(SHA), Shanghai Pudong (PVG), Tianjin (TSN), Wuhan (WUH),
Xi'an (XIY) or Xiamen (XMN) for a max. transit time of 72
hours, starting from 00:01 on the day following the day of
entry.
- at Guilin (KWL), Harbin (HRB), Kunming (KMG) or Shenyang
(SHE) for a max. transit time of 72 hours;


However, although several non-official sources substantiate this distinction, I cannot find any official confirmation of this. Does anyone have any experience in doing this kind of transit?
