Any British citizen can enter the US on the Visa waiver program for 3 months as a tourist only--working is not allowed.
Everybody. If you are a US citizen you can go without a passport. If you are not a US citizen you can enter with proper passport and with an US visa.
does a citizen of Mexico need a passport to go from the us to Mexico and back? He is legal to be in us but not a us citizen.
If you are ONLY a citizen of El Salvador, currently live in the US and have no residencies or work permits you may go to Europe if you never want to come back to America. Now if you live in El Salvador and want to VIST Europe, well you'll have to check your own laws on that
You go to immigration and start the paper work.
Yes, lots of people from Europe go to the US.
Can a is felon go to Canada if they marry a Canadian citizen
Yes. Both my daughters were born in FRance, but because I am a US citizen, so are they; but you have to go to the US Embassy of the country born in and request a Consular Report of Birth Abroad.

There would be procedures to go through, but the answer is yes.
