Farm Labor Contractor Registration Act Amendments of 1981

Farm Labor Contractor Registration Act Amendments of 1981 - Amends the Farm Labor Contractor Registration Act of 1963 to exempt from the definition of "farm labor contractor": (1) any person supplying migrant workers for employment in his own agricultural operation (currently the employer must personally engage in such hiring); (2) bona fide employees who perform such activity for their employer (currently full-time or regular employees who engage only incidentally in such activity); (3) any person who supplies students or other persons whose principal occupation is nonagricultural to perform certain seed industry work (currently only applies to corn and sorghum with a maximum four-week work period); and (4) nonprofit or cooperative associations of farmers, growers, or ranchers and their employees.

Defines the terms "for such person's own operation" and "bona fide employee" for purposes of such Act.

Redefines "migrant worker" to mean a seasonal or temporary agricultural worker who can not normally return to his or her domicile after each working day (currently anyone employed in agriculture).
