Hi, yes you can. Irrespective of the university you have to clear specific entrance exams for specific positions.

Hi,
Since majority of the universities in US prefers a four year Bachelor's degree obtaining a lateral entry after the second year will be difficult. You should get email the universities directly for the university specific requirements for your case.

Dear Naveen,
Without any work experience, you can not go to US or Australia. So kindly gain at least 2 years of experience and then think about it.
Good wishes.

The USA is the hub for MS and would be a much better option than studying in Ireland. It has a much broader base of colleges offering courses in MS, and degrees from the US are most definitely recognized across the globe. Some of the industries one can get involved with after completing M.Sc in biotechnology are as follows:
1) Research Institutes
2) Education
3) Hospitals
4) Power industries
5) Aviation Industry

You are eligible toapplying Engineering graduation degree in USA Universities after Diploma in Engineering as you meet min 12 years education requirements in USA Universities but you may not get lateral entry admission in second year of Engineering as in India.
