PROBLEM: My brother who is from Bangladesh got deported from the UK back in 2009 for working illegally while being a student. His old passport was not machine readable.

Since then he has obtained a new clean machine-readable passport (no record of previous visas) and visited countries like Thailand, Singapore, India, Malaysia. He is now planning to visit the US to attend my college graduation.

If he checks the box to say that he was never deported from any countries, is there any way they can find out about this?

SOLUTION: Deported from UK but got a fresh clean passport. Will the US know?

PROBLEM: I will be landing in Victoria Falls and starting a truck tour which goes through Zambia and back into Zimbabwe. When I called the Zimbabwe embassy in London, they said that I will need to get two single entry visas at the border ($50 each). They didn't want to give me any info on multiple entry visas. Is it possible to get one at the port of entry?

SOLUTION: Can a New Zealander get a multi entry visa for Zimbabwe on arival?

PROBLEM: I am going to the Netherlands and might need to get a train. (Between Eindhoven and Amsterdam). On www.ns.nl (the large train operator that does that route), they list the price as 17.90ish. That's for booking it online.

However, I'm not sure what price it'd be if I were to turn up on the day and buy a ticket for the next train going that way.

Here in Ireland if you book train tickets online in advance, it's much cheaper than if you arrive in the train station and want to buy a ticket for the next train. (e.g. 20 online vs. 60 last minute in some cases). Is this the same in the Netherlands with NS or is it the same price regardless of when you book?

Update I don't care what sort of train to take, I just want to get from Eindhoven to Amsterdam.

Money isn't too much of an issue, I just don't want to be asked to pay 50 per ticket when I could have got it for <20 had I only booked online!

SOLUTION:
Is it cheaper to book Dutch train tickets online in advance compared to paying on the day?
