Given a travel related situation, and given a specific question about the situation, summarize the question into a title

[Q]: I will be visiting Portland on a business trip, and will be able to sightsee only at night. Is it safe to leave my hotel located downtown and walk around?

[A]: Is it safe to walk around downtown Portland, Oregon (USA) at night?

[Q]: My friend and I arrive to the HK airport (by international flights) with a 40-minute difference. Where is the best place for us to meet? I've heard that all flights arrive to terminal 1. Is it a good idea to meet at some specific place in Terminal 1, before going through the immigration and customs? If so, where exactly? (The map says there are 8 levels, and I'm not sure which level and place is most optimal.)

[A]: Where to meet a travel partner at the Hong Kong airport?

[Q]: Here's my situation. I am currently in France on an internship visa (different than a business and tourist visa) which ends next month. I'm interested in doing some traveling afterwards, ideally on a 90-day Schengen tourist visa. I'm willing to hop over to a non-Schengen country (like the UK) for a couple days and then come back to get the tourist visa if necessary.

This post seems similar to my question, except the OP is trying to get the tourist visa without leaving the Schengen area.

Is this allowed? Will the border patrol still give me the tourist visa after my internship visa expires? Will it work through the UK or should I go through another non-Schengen country? I have a USA passport.

[A]:
Can I start a tourist Schengen visit after my long-term Schengen visa is over?
