Whenever I came to the US, I have always been asked what the purpose of my visit is. So basically if I am being asked that question at the border, and I tell them that "I wanna visit my boyfriend" (only visit), but I also marry during my visit, and start the CR1 process after I return to my country, it all will cause an issue for the marriage visa process or at the border again when I want to visit on a tourist visa again while my CR1 is pending?
