I have to admit its pretty surprising how people have the misconception that life in America will be easy without proper skills or a decent amount of savings and that too considering the state of the US economy at the moment even with the NYSE and DOW shooting up (which I feel is equivalent to pumping air in a punctured tyre).
pawanlamichhane, out of curiosity why do you even want to move to America at the age of 19? And that too with the added responsibility of a wife and without any work experience or higher education?
As britsimon said on another thread, this isn't simply about getting a visa and your life being set because it is way much more than that.
Rents (depending on the area) can be anywhere from $700 (in a total dump of a neighbourhood full of crime) to $1,500 in a decent neighbourhood. The only exception is if you are staying with family or if you are lodger paying for only a room in that house.
Food expenses - britsimon isn't referring to eating out in restaurants man. A restaurant bill itself there can hit between $50 to $100 depending on where you eat. Walmart is supposed to be the cheapest supermarket and even they have increased their prices. People spend up to $1,000 on food at home. I mean lets face it are you going to sit and starve yourself to save money? The only exception is if you are staying with family or someone who knows you and is willing to foot the bill for your food or you pitch in towards food expenses.
Then you have things like utility bills (electricity, water, gas etc.) unless you choose to sit in the dark and without heating during the winter to save money.
Health insurance - this is the killer (and britsimon is sharing his valuable insight on this with me on another thread - thanks britsimon) because this is the most expensive part of expenses. Supposing you or your wife fall sick and need medical care, what will you do? Hospitals will not take you in without medical insurance or upfront payment. I know this for a fact because when my brother fell sick in Florida 10 years ago, we had to take him to hospital and because our health insurance did not have USA coverage, we had to pay $2,000 (if I recall correctly) for overnight emergency care.
Car expenses - America literally runs on cars. It is an absolute necessity to have a car in America otherwise you will be totally handicapped so first you need to buy a car, then fork out the insurance, then fork out money to pay for petrol. Gas mileage is the mentality for most people in a America. The more unfriendly a car is on gas mileage the more money it will cost you.
Higher education - with what I make of your financial situation it seems you need all the help you can get. The vast majority of foreign students who come to universities in America are on financial aid and they have to pay this money back. Not only that, there are also conditions placed on that financial aid like maintaining a certain level of grades. As britsimon said, first you need to work and save up, then pay the education fees plus extras for books and being a permanent resident would mean having a credit history in order to apply for student loans which you won't have when you enter America so you'd have to pay your own way through initially.
To reiterate/echo britsimon's words, it is all about perseverance/hard work, a positive attitude, lack of fear, an understanding of the reality that is America, a good education background, skilled work experience and money money money and more money.
The reason many people flop when they go to America is because they didn't understand the reality beforehand and weren't prepared so reality slapped them in the face...
Better think this move to America carefully my friend otherwise you may make a mistake which you would regret. A Green Card doesn't mean life in America will be a picnic...
