Since it is a state sponsored college, then there are two tiers of tuition. For in-state residents, the cost is relatively reasonable. For out-of-state students and international students, the tuition is much higher.

Based on $5,000 tuition, you must be looking at the wrong tuition rate.

Here is the tuition for the University of California, San Diego (a state sponsored 4 years college); http://students.ucsd.edu/finances/financial-aid/budgeting/undergrad-2012-13.html

California residents: $13,234 tuition.

Non-California residents (that's you): $13,234 tuition + $22,878 supplemental tuition = $36,112.

UCSD would charge you $36,112 tuition for each year.

I also suspect that the OP looked at the in-state tuition. But the I-20 should include the correct tuition, unless the school really screws it up. OP do you mind telling us the schools name? I understand if you don't want to.
