Postgraduate studies

I know importance about postgraduating, but I don't have theme or subject clear yet but my project is study in other country but one biggest barrier is language. So I was considering about some countries where people speak spanish like Spain besides there we can find good renown university about sociology. Also I considered take some course of english because is very important in most countries. So, if a take that course probably decided by other options like United States.

I have in mind studies about gender, related with anthropology and others that I don't know yet, for example, social inequality. The first and second point are inspired in classes of last year I really liked and I feel necessity to study and have more knowledge about them and before that I never was thinking about that form or adopted position more critique.  

About type of study I have the idea to study "full time" (sounds difficult but not impossible) but problem is how can get resources, only I have savings in my account but in my opinion is not enough. Other option is work after finish career and saving until have a good amount of money. And if all options fail, I can study in Chile but my idea is study abroad. But still is too soon to overthink and overwhelmed even I don't know if a I will finish the career.
