The top employers on this list — Tata, Cognizant, Wipro and Infosys (with the exception of IBM India Private Limited ranked #8 on H-1Bs) are also the top users of new H-1B visa application approvals in fiscal year 2012 according to Computerworld.

An L-1 employee sent to work temporarily in the United States by the petitioning employer must qualify in one of two subcategories:

• L-1A – an alien performing services in a managerial or executive capacity.
• L-1B – an alien performing services as a specialized knowledge worker.

Most L-1 petitions are adjudicated by Immigration Services Officers (ISOs) at the California and Vermont Service Centers. After USCIS approves a petition for a beneficiary who is overseas, a Department of State (DOS) consular officer interviews the individual at a U.S. consulate or embassy. Immigration Officers at ports of entry have the last say on whether an alien carrying a visa is allowed entry into the United States.
