Hi! I am an Indian passport holder on a B2 visa. I came to the US due to a family exigency in March 2021. I received admission in a doctoral program last week, I had applied for it in December 2020. I want to change my visa status from B2 to F1 as my classes start in Fall. I was planning on going to the US Consulate in Mexico or Canada as India is not possible due to Covid surge. But even Mexico and Canada consulates are only taking emergency cases and the wait time is not visible online. Please guide on what would be the best option for me.
