<p>Don't take the TOEFL if you got a good CR score. It's a waste of $150 and several hours of time. Use the money to pay for college (maybe a book) and the time to write your essays.</p>
<p>Unless you apply to a need-blind school, there shouldn't be quotas against international students living on an H-4. Need-blind schools might have quotas for internationals that need financial aid, and admissions don't know who needs financial aid or not from the international pool. There is a quota (I think) for those needing an I-20 and apply for a F-1 visa, but the H-4 visa should preclude the necessity for an I-20. Chances should be similar to those who are domestic applicants since you aren't requesting financial aid. For schools low on international students, your chances might even be higher.</p>
