I am a Nepalese student and have a F-1 visa but I came in US a bit before my earliest admission date of the university. So, I was provided with a I-193 waiver and was told to exit and re-enter US with it. I am in Texas right now with B-2 status. I am planing a 1-day trip to mexico for the re-entry. So, will I need to apply for a Mexican visa or not? Or do I need anything else? I have my F-1 visa, my I-20 and my waiver with me and I want to know what I have to do now.
