HR Professionals who deal with United States immigration matters may be aware that the latest version of Form I-129 now includes an export control attestation; this export control attestation became effective on February 20, 2011. As of that date, employers seeking to petition H-1B, H-1B1, L-1 or O-1A (O-1A includes extraordinary ability in the sciences, arts, education, business, or athletics) workers must now answer the attestation. Unfortunately, determining the applicability of U.S. export restrictions can be a complicated task and may require a legal opinion from a lawyer who has experience in this area.
