OMB Circular A-21, J.41. Scholarships and student aid costs
a. Costs of scholarships, fellowships, and other programs of student aid are allowable only when the purpose of the sponsored agreement is to provide training to selected participants and the charge is approved by the sponsoring agency. However, tuition remission and other forms of compensation paid as, or in lieu of, wages to students performing necessary work are allowable provided that (1) there is a bona fide employer-employee relationship between the student and the institution for the work performed, (2) the tuition or other payments are reasonable compensation for the work performed and are conditioned explicitly upon the performance of necessary work, and (3) it is the institution's practice to similarly compensate students in nonsponsored as well as sponsored activities.

IRS Publication 520 (Scholarships and Fellowships)
Wages and other compensation paid to a nonresident alien for services performed as an employee are usually subject to graduated withholding at the same rates as resident aliens and U.S. citizens. Therefore, your compensation, unless it is specifically excluded from the term "wages" by law, or is exempt from tax by treaty, is subject to graduated withholding. . .

If you work as an employee in the United States, you must pay social security and Medicare taxes in most cases. Your payments of these taxes contribute to your coverage under the U.S. social security system. Social security coverage provides retirement benefits and medical insurance (Medicare) benefits to individuals who meet certain eligibility requirements...All taxable wages are subject to Medicare tax...Your employer must deduct these taxes even if you do not expect to qualify for social security or Medicare benefits. You can claim a credit for excess social security tax on your income tax return if you have more than one employer and the amount deducted from your combined wages for 1999 is more than $4,501.20.
