I'm a low-income international student studying astrophysics. I have been made an offer for a PhD program, however, due to limited astro funding it is unclear whether I will be able to do astro research so I would need to switch my research area. The university is in a city that I've wanted to move to my whole life so I'm worried that if I decline, I'm missing a once-in-a-lifetime opportunity. I am more interested in astro than other things, but am not super passionate to the degree that some other people are, so I would potentially consider other fields.
I am also applying for an OPT to see if I can do any astro post-bac programs, but it seems those might be even more competitive this year. I will need to stay an additional month or more to figure out the OPT situation, and might need someone to mail my EAD to me in that case.
Third option is to drop this whole situation and move back home, apply to astro MSc programs in the EU (probably Germany), where I would have to pay a very minimal tuition fee and could possibly work part-time to pay for rent, though I'm not sure how easy that will be, considering I don't speak the language. I am confident I can get into a good program there, but if I wanted to come back to the US I would probably need to reapply to PhD programs if I decide I still want to do that.
I am currently just quite burnt out and don't know what I want to do so I would appreciate any advice.
