hello and welcome on board !
Please note that I have created this new thread from your post on the Grenada forum so that members settled here might help you.
So, for a good start, you need to choose whether you wish to work there or study as these are 2 different things, formalities will differ and your visa as well.
For Studies, the most practical way is to google search schools and universities and send them a message through their website. They will provide you all the necessary information on applications, fees and visa.
For work, it is more complicated, it requires to have skills and professional experience that are in demand in the country so that you may find an employer. Maybe you could elaborate on your skills and qualifications.
