Dear,

Stipend is something you get after you complete a certain internship for certain duration. Stipends are given on monthly basis. So, if you are doing an internship in your final year then you will be getting the stipend which is mentioned in your offer letter.  Stipend is not something you get when you reach final year, rather it is like a salary you get after your internship. You can get it for any internship that you are pursuing.

Hope this helps!
