Yes, UEM Kolkata is indeed strict in terms of your outer appearance. These may include a white sleeve shirt with UEM emblem, grey trousers, formal leather shoes, a tie, and an ID card. All of these are a must for every university student and member.
If you miss one of these things, the security officers will return you home from the main gate itself. You cannot even enter without a uniform on vacations whether you are working at the management office or library.
Make sure that you are properly dressed and especially don’t forget or lose your ID card. Even if you lost it then you will have to submit another application and you might not be accepted by the guards inside.
