Hello, what are the foreign opportunities that I can consider directly after graduating from college? Are there any other firms, except for the UK ones, which are open to taking Indian students?

You will have to get qualified in each of those jurisdictions and unlike UK based firms, your employer will not hire you except as a paralegal till you can get such qualification.

MCKINSEY, but so far they have only hired NLSIU grads.

How's that a foreign opportunity? Most of those people still work in India. What next, a Deloitte hire?
