Hi Kiran,

To be eligible to fill the MH CET form, it is mandatory that the candidate is an Indian National. So, if he/she was born in India and then relocated to the Middle East for his/her studies then that will not be an issue. However, if he/she is a citizen of the Middle east then they cannot sit for the exam. 

Please kindly read through the following article on MH CET that explains in detail the guidelines, important dates and eligibility criteria. It will help you understand the process better.
