Diploma

Hi Sushil,
A two year master degree course is better for PR. Your work permit duration will also depend on the duration of your course so a master degree is always better but a job will depend on your skills irrespective of the program you pursue or degree you obtain. Best of Luck.

Yes, you can. But, you will have to take NATA/JEE entrance exams.

My advise would be to go for Engineering directly. Diploma route would not get you any added benefits.

You can do M.Sc in botany, zoology or professional subjects like biotech., microbiology, biochemistry.
If your interest is in agriculture then you can do PG in agriculture.
I suggest you not to persue diploma as doing diploma will not help you in getting job and you will spend your 1 year also.
