How big is Nepalese community in New Hampshire. I am looking to move around Portsmouth or Dover area.

What will be your business.
You will find different kind of breedings, pure politicians to voters nature.
There is big industry running within international people, you will know what I am talking about . You better buy or rent a house with extra room that may help you as as a milking cow in long run.

Thank you for your reply @magorkhe1. Actually, I am not looking to open any business. I will be moving for a job. Can you please detail on why buying house would be a good decision. I see the property taxes are pretty high over there.

That is NH , live free or die, no state tax but property tax is amazingly higher. Suggest to be there first live couple months first before making any decision.

Lakeside Ji, I was in NH a little while ago to visit a friend of mine. I saw lots of South Indians in the grocery stores and malls. I came to know that they are in the IT jobs. Are you going there in the IT job too ?
Good luck to you !
