When you start to plan about funding for your tuition and other living expenses in the United States, keep in mind that you cannot count on working in the US unless you have been granted a teaching or research assistantship. Immigration regulations are very strict with respect to working while carrying a student visa, and when you submit evidence of your financial resources, you cannot rely on potential income. The income on which you base your application must be assured, and it must be equal to or exceed the costs of the first year of your studies.
