While many institutions show their best face when trying to attract students, it is in your interest to do some investigation.
After all, it makes no sense going and working hard for a degree only to find out that your island does not recognise the qualification and you're basically back at square one.
The national accreditation body in your country is usually a good place to start. They can tell you whether the institution's qualifications are recognised or whether you will have to do any translation courses to supplement your training.
