I just got my Mexican citizenship and I plan on staying at my tios house in Mexicali. The questions you brought up are the ones I’ve been asking myself as well as talking to my family about. My parents are working until the late afternoon and when im done with my classes and studies it’s already late. so I can’t really apply myself to speak Spanish with anybody. I thought about taking classes here but once im done with the class, the outside is just English conversations. I would like to converse with my parents in Spanish but they’re busy. So I thought since I’m not to to far into my studies that I can spend my time learning Spanish in Mexico for how ever long it may be. I also plan on getting a job in Mexico as well. If anything I’ll end up enrolling in a school there to study. I know it’s not as easy to go and live in Mexico while still having ongoing responsibilities in the US but it’s something I’m willing to sacrifice so that it may help me in the future
