Canadian Citizen becoming a US citizen?Canadian Citizen becoming a US citizen?

why would she ever want to be an american

Becoming a citizen will take a very long time. For now, her best shot is probably an employment visa. If she doesn't have an immediate family member who is a US citizen, then she will have to apply for an employment visa. For the vast majority she will need to have a labor certification from the employer.

What kind of job does she have?

There are multiple categories of employment US Immigration considers, from highest preference to lowest:

E1: Superstars. These are people like world-renowned scientists, international sports stars, and Academy Award winning actors. These people do not need a job offer. Also in this category are elite professors from top universities, and executives who have worked for an international branch of a US employer. These people do need a job offer.

E2: Professionals with advanced degrees and those holding exceptional ability in the arts, sciences, or business. These are researchers and engineers, also actors who plan to appear on Broadway, and top level executives who are taking control of a US company. These people (and lower categories) must have a labor certification.

E3: Skilled workers in a job requiring at least two years experience, professionals with a four year degree, and other workers (everyone else). These are nurses, middle level management, machinists, and landscapers.

E4: Special Immigrants. None of these are likely to apply, unless she is a minister.

Yes. Both the US and Canada allow dual citizenship. I am a dual citizen US and Ireland. My wife is a dual citizen also. We are both well over the age of majority (AARP members).

Really, unless she has a degree accepted for a TN Visa, she has to marry an American.

When i was a kid it was called a green card. That is what i think your mom needs.
