Hello, I have a quiestion, I have a dental practice in Mexico city an a while back I started going out with a woman from the U.S. Recently I decided to open a second office in Tijuana to be closer to her, My question can In work in Tijuana, enter the U.S. on the evening or night, spend the night in her apartment and go to work in the morning and have this routine for a period of 3 to 4 months? I would have to go back to Mexico city for a period of 4 to 6 months to take care of my other practice. I currently have a B1/B2 visa, Tahnk you for your Replies!!!
