Hello 

If your main aim is to work in foriegn then there are a few things that you must know which are basically that you must be sure of where you want to go for the job,what you want to become,which is the area of your interest.Its better to analyse these things first and then think of doing the course related to it,rather than doing a course here and then later struggling for jobs outside.There are some countries that give preferece to the candidates that have done courses required for the job over the other candidates.Its advised to choose the appropriate course after checking suitable posts for the same.

Thank you
