Travel Document Express

I think a trip from Belfast to London with National Express, I do not find all the information in the documents that I take with me, nobody knows if such transport is stopped by immigration at a time or how it works ?
I need to know if I need my passport, identity card, money, etc., since I am not an EU citizen.

Because you are not a citizen of the European Union, you will probably need your passport and visa (if you had to get one to go to Belfast) identification and prove that you have right to enter the country without these you will not be allowed to enter the mainland United Kingdom.

Belfast is in the United Kingdom, so you should not have all the documents.

The money would be a good idea, and the realization of your passport and visa you could get help for reasons of identity, just in case.

ladyni said that, sterling silver and id.

It's always a good idea to bring id
you need English money
