sauravojha - I guess the answer to your question is difficult since I don't know your line of work & your long term plans. Anyways here's my attempt. Northern California is an excellent choice for immigrants. California is the most diverse and also the most populated state in US. Besides this, in my opinion San Francisco is the most beautiful city in US. It has character.....not just tall bldgs. Being such a huge state & its geographic location, you can enjoy anything like beach, snow in lake Tahoe, desert down south, and the best part of Northern California is the weather. No snow in Bay area...Foggy mornings in the winter time...mountains in your sight....will remind you of Nepal...:) As for RN in CA…depends on which city. To get some idea of salaries goto www.salary.com. In the Midwest RNs get $35 - $40 per hour and then there is always lots of overtime for nursing jobs…Good Luck!
