thank you all for your answers, but do you know what are the job prospects for non-native speakers with CELTA?
I checked subforum 'Jobs' below, and native speakers, mostly British and American citizens are preferred.
I think it depends on where you are looking for the job.
If you want to get it in an English speaking country then probably it would be harder for you to get it.
I suppose it would be easier to get a job as a teacher in countries like Norway, Sweden where English is not their first language; that's my opinion. You can also apply for a teaching position in your homeland....
