I am a U.S Citizen, and my boyfriend lives in Mexico. Is there a way he can come to the U.S besides getting a Visa?

If your boyfriend wishes to do so, he can apply for a visitors visa to come to the US to visit for short periods of time. That can be done immediately.  The issuance of it is in the discretion of an American consular officer. If you are contemplating that he will stay in the US for longer than short periods of visit, you would have to wait until he goes through the process of applying for a student visa, which is again issued in the discretion of a consular officer. If you are thinking marriage, you might apply for him under either K-1 fiancé petition or, if you marry him in Mexico, directly for his residence status.  Those are longer processes.  Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
