I am not sure what the TM is looking for in our replies.
When we talk about the difference between Desi women and NRI women, one thing is obvious. Foreign women are definitely outgoing and outspoken. However that means only that they wouldn't be scared talking to males also and they could mix up with males and strangers and they could be good friends. This could not be seen in Indian females who will be scared talking to males if they are of traditional types. However there are exceptions in Indian females also.
As far 'getting' an NRI female what are you looking for? Looking for an NRI woman for marriage, I assume. That could be quite possible if you work for that focusing on that line. Find out the stuff within you which is definitely there to impress women and work accordingly.
