Unfortunately, getting funding as an international student in the US is pretty challenging since most scholarships and financial aid are reserved for citizens or green card holders.
Regarding visas, you’ll likely need an M-1 or F-1 student visa to attend flight school. I came over on an F-1 myself, and while it’s perfect for studying, you’ll want to start thinking about long-term options like an H-1B work visa or a green card if you plan to stay and work in the US. The whole process can take a while, but if you’re determined, it’s definitely doable!
