I have been teaching for the past 4 years ( I am not certified) but I am bilingual (Spanish) I was wanting to know if it is costly or even possible for me to teach abroad and if it is costly? If so are there any cheaper alternatives?
Welcome to the forum. The cost of living depends on the location you choose to teach, for example you can have a look at the article on cost of living for Abu Dhabi (https://www.teachaway.com/teaching-jobs-abroad?loc=All&jcat=ESL+Teaching&sub=All&lvl=All) . Do keep in mind that all postings will note under teaching benefits what living/accommodation allowance you will receive.
I would also encourage you to do your own research on cost of living for the locations you are interested in
Good luck with your search
