You would follow the same process as an applicant from any other country (there's no specific process for US applicants). See the link provided to you above for information about Canada's economic immigration programs. Generally speaking, these immigration programs favour young skilled workers.

You can try calculating your points to see what chance you have of being selected. Right now you need 440+ points to be picked.
