Greetings to you,

As per your rank in JEE Mains 2019 and in accordance with your OBC-NCL category, you cannot get a seat in any of the NITs, IIITs or GFTIs. Most of the GFTIs for OBC-NCL candidates closes around 16000 category rank (on the safer side). I would suggest you to try for private institutions that conduct their own admission tests or you can apply for state colleges. Good luck.
