Benefits based on services, substantially all of which consist of participating in sports or athletic events or training or preparing to so participate, shall not be paid to an individual for any week of unemployment which begins during the period between two successive sport seasons, or similar periods, if the individual performed such services in the first of such seasons or similar periods and there is a reasonable assurance that such individual will perform such services in the later of such seasons or similar periods.B. Benefits shall not be payable for weeks of unemployment beginning on and after January 1, 1978, on the basis of services performed by an alien unless such alien is an individual who was lawfully admitted for permanent residence at the time such services were performed, was lawfully present for purposes of performing such services, or was permanently residing in the United States under color of law at the time such services were performed (including an alien who was lawfully present in the United States as a result of the application of the provisions of section 203(a)(7) or section 212(d)(5) of the immigration and nationality act). Any data or information required of individuals applying for benefits to determine whether benefits are not payable to them because of their alien status shall be uniformly required from all applicants for benefits. In the case of an individual whose application for benefits would otherwise be approved, no determination that benefits to such individual are not payable because of his alien status shall be made except upon a preponderance of the evidence.
