Your spouse, as a US citizen, will need to file form I-130 (USCIS) for his stepson. It explicitly states that the marriage must happen before your son's 18th birthday in order to use this form. Otherwise, your son will need to wait until you are a citizen (at least 3 years) before you can petition for him.
You are going to need to contact the Immigration & Naturalization Service.
Getting married to an American citizen.
They are officially married. One spouse can sponsor the other for immigration to his or her country.
Yes. Easily. Especially being a UK citizen, it does not require the UK citizen to go to the US if needed for the immigration process.
You go to immigration and start the paper work.
they would call in less than six months for an interview to see if you are really married to the American citizen. then they will issue a conditional permanent card for two years. when that card expires you would have to go to another interview to see if you do not commit marriage fraud, if you pass they will issue a permanent card for ten years.
Not automatically. After being married to a US citizen for two years the legal foreign national spouse can apply for citizenship. Visit the United States Citizenship and Immigration Service website for specific information.
Usually in an airplane.

No, the Canadian has to be married to the American in order to live or work in America. Because you have to be married to an American to get a green card in order to do that.
The US Immigration Service handles those matters. They will tell you who, what, and why procedures and papers (documents) will be needed.
he will stay American citizen....he has to apply to become a Canadian citizen or his wife has to apply for him and will have to tell the court that she has married him
