I am a Canadian citizen wanting to move to the US with my boyfriend. We aren't ready to get married. What are our options?

Everything is going to depend on what your professional qualifications are.  As a Canadian you are eligible to enter the US as a Treaty National if you are a member of certain professions and have a job offer in the US to practice  that occupation.  The offer can be from your boyfriend or another potential employer.  The details of this are complex and you would be best off scheduling a telephonic appointment and discussing the particulars over the phone.   Alternatively, assuming you do have marriage plans, he could file a fiance visa petition for you which would result in your being able to enter the US as his fiance.  You could remain here for 90 days and would have to then either marry him and file your documents to stay permanently on sa green card, or, if you decide not to marry, you would have to leave the US.   If you would like to discuss your alternatives in more detail, please feel free to make a telephonic appointment by calling our office at (619) 291-1112.   Best regards, Jan Joseph Bejar, Esq.
