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

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?

Q: I am in Maple Shade, New Jersey and would like to visit Niagara Falls, NY (US side) by this month, after which it will get very cold and I would wait till the summer next year. 

Will the fall have enormous amounts of water now, like it has during the summers? We are planning to take the Amtrak train to go there as it is 8+ hours drive from here. 


A: Is the amount of water going over Niagara Falls very different in September compared to summer?

Q: I am currently in Saint Petersburg on a tourist visa (I'm French). I arrived on Tuesday and I'm leaving on Wednesday morning, so I will be a total of 7 working days in Russia, including the arrival and departure days.
I assumed I wouldn't need to register my visa, so I didn't, and neither the hostel where I'm staying nor my sponsor told me anything about it either.

Now I just noticed that because of the world cup the rules have changed, and I was actually supposed to register it within 24 hours, so it's obviously too late now.

What should I do? Should I go try to register it anyway before leaving (and pay whatever fine there is) or should I just forget about it and hope they won't care? Is there a risk they will prevent me from leaving Russia? 

In case that matters, I will be leaving by train to Finland (and on the last day of my visa). 


A:
I did not register my Russian visa, what should I do?
