I suggest you check what you need, collect information for wp (such as limitations, upcoming updates w10, about the availability of apps,

Even if you don't live in US you can have great support in Cortana. I live in Greece and I have change my settings to U.S. and I have almost all the advantages.
If you are to buy a wp, I suggest you buy one from Nokia, or MSFT as they tend to offer more features (such as firmware and loyalty, exclusive apps and phones that last longer). From my personal experience I have a Lumia 920 for more than 1,5 y and it still like brand new, with few invisible scratches (I tend to keep my phone with my keys). Also MSFT (or previously Nokia) have many good budget phones better, stronger and cheaper than android (and in specs)
Unfortunately if you want some official apps, such as from google you wont find them, there are some alternative but I don't know I they are good. I am extremely pleased by MSFT services (OneDrive, translator, msn apps etc). For youtube there are apps even better than the official from any OS, like mytube.
As I am also a student I believe you will be pleased with what wp can offer you. Also I strongly suggest you to check the upcoming update w10 and see the changes it will offer.
(piece of advice avoid buying a phone with a contract/ carrier if you are in U.S., its better if you buy an unlocked, carrier free phone)
