Start with shortlisting the collegs you are interested to take admission in abroad. Also shortlist the location you want to take admission in. Then there is english proficiency exam you will be required to give and other required exam. Each college has itw own criteria.

Once you meet their score cutoff then you can get the student visa and further admission details. Later if you had a good academic prospect in the studies while the internship they can  hire you and therfore you have good chances to get settled there.

Hope this helps.
