The total annual expenses i.e. fees, books, boarding and lodging will vary from $15,000 to $40,000 depending upon the universities. Majority of GEC students are placed in government supported universities that provide quality education, where the tuition fees are very nominal and applicants have high prospects of getting financial aids like tuition fee waivers, research/teaching/graduate assistantships.
Most of the students get to U.S with just enough money to last a semester i.e. about $10000 in hand. In addition there is financial support available in the form of assistant ships (both research and teaching), tuition waivers and it is possible to work on campus.
Having a bank account will be convenient for money transactions. Many college students appreciate the convenience of a MAC (Money Access Card) or ATM (Automatic Teller Machine) card. If you have an ATM card from a bank in your home country, ask whether the U.S. bank will honor it; some Personal Identification Numbers (PINs) cross national borders, while others do not. Credit cards and Debit cards are convenient payment options. They help to maintain good financial records and also serve to remind you of the money you spend.
