News regarding U.S. Embassy in Chennai, India
The U.S. Embassy in Chennai, India has changed the types of cases that it handles. As of January 1, 2012, the U.S. Embassy in Chennai, India no longer handles any permanent immigrant visa applications. Instead, the U.S. Embassy in Chennai, India now will ONLY handle non-immigrant visas, such as B-1 / B-2's (i.e. visitor visas for business or pleasure), student visas, H-1B and other H-1 visas and H-4's for dependents, and other work visas.
The U.S. Embassy in Chennai, India has now become the ONLY U.S. Embassy in all of India that handles L-1 visas. L-1 visas are intra-company visas, which means that a foreign company has opened a branch in the U.S. and wants to transfer one of its main employees (executive or manager) or owner / President to the U.S. in order to expand the business. The foreign business MUST remain open and active in order to qualify for the L-1 visa.
The USCIS has indicated that it wishes to centralize applications so that fraud is reduced and so that Officers can become extremely efficient in one type of case. It seems that centralizing L-1 applications for all of India at only the U.S. Embassy in Chennai, India is a good step to increasing efficiency, as the Officers are or will soon become experts on L-1 visas. L-1 visas are extremely complicated visas, and so it is good for the Officers to become proficient in one type of visa to avoid incorrect applications of law or incorrect denials.
Applicants who had an immigrant visa appointment already at the U.S. Embassy in Chennai, India need not worry, as the U.S. Embassy has indicated that it intends to complete action on those pending cases by March 30, 2012.
