The United Kingdom was the only place I traveled to with my fiancé where I stayed for 6 months, because we also went to Scotland and visited several cities. After that, we traveled to Switzerland, France, and Prague, and stayed there for about 20 days in total, together with our families. I returned to my home country right after. I have never worked illegally nor had any issues with the police there.
I've never been to the United States with my fiancé
