Self employed

Per this excerpt from an IRS article on Fulbright Grants, such income if for teaching abroad is normally considered wage income as opposed to self-employment income:

If it is wage income, you cannot deduct expenses associated with it.

What distinguishes wage income from self-employment income is typically the amount of control the employer has over the worker. If the worker can set his own hours, uses his own tools and other work resources, performs similar services for other employers, in general behaves as a self-employed business person then the work may be considered self-employment as opposed to salary work. If so, you can treat the income as self-employment income and deduct expenses that are ordinary and necessary for the conduct of the business.
