Hello aspirant,

If an institution is not recognised by UGC then it might create problems for you in the future in pursuing a career and opting or applying for a job. This is because, if an institution is not recognised by UGC then it is illegal and cannot issue certificate due to it being illegal. The certificate or degree is would provide would be illegal and most likely to prevent you for getting a good job at your preferences.  

I hope this helped. 

All the best!!
