Unfortunately, without a FICO score or credit rating here in the United States, you may be restricted to purchasing a home worth between only about $300 to $400,000, and at least here in Santa Clara County that is going to be tough to impossible unless you are willing to buy a condominium rather than a single family home with a lot and yard.
The important issue to resolve before you begin looking and before you talk with a real estate agent is financing and availability of credit. For this, you will need the advice and time of a loan officer or banker who will ask to review your credit history and income information to document sources and uses of cash. Once you know if you can obtain financing and how much you can get, you can get out there to buy a home.
Right now talk with a banker for advice. It might be best to begin with a banker in the country where you work to see if funding is available for international purchases. If the bank is a multi-national organization, they will have someone within the bank who can assist you or they can refer you to a lender here in the United States. Unfortunately, working for a US owned multinational corporation Is often insufficient to obtain either a credit history in the US or financing here in this country without tax returns and proof of domestically generated income (money earned in the US).
