Hello guys, how are you?
I hope you are all doing well.
I’m making that post because i need to get some little things off my chest and because i think that some advices could be usefull.
I’m 20y from Brazil, ex IT major student but i didn’t identify myself with the thing and now i’m pretty decided on going to the medschool and becoming one doctor following one international career path.
I need to work for a few years more to help my family to afford for my medschool costs so probably i’m just beginning the medschool around my 22 or 23.
I’m feeling extremely overloaded and pressed with all the research that i’m going to have to be doing for that reason.
First, because i had tought mainly in becoming a doctor in the U.S, but i’m actually confused if that’s the better choice for me, i know that some other countries like australia, canada, or even switzerland or others offers competitives salaries as well.
I’m definetly quite worried about all of that because i know how is important to build one strong CV since the first day of the medschool and how it can impact on your chances of getting one residency spot, wherever you end up deciding to try it.
So i don’t know exactly which country i would decide to follow for my whole career to practice the medicine, plus i’m unsure about which specialty i would like to choice, it feels like i would need some advisor or lamp genius (sorry for the joke).
Do someone here can offer any good advice for that young guy?
It’s just a thing about which country should i choose, where can i get the better salaries, which are my chances as one IMG, (plus i still didn’t decide which country or university i’m getting into medschool). And all of that.
If someone can say anything to help me to get my mind a little bit clearer i would be gratefull, thank you very much.
