I am planning to stay couple of days after expiration of my L1 visa, can I just apply for ESTA or I really need to go through the procedure of changing my visa to B2 status (trying to avoid additional costs and bureaucracy)
You cannot do a change of status to ESTA, you would have to leave the country.
The above is intended only as general information, and does not constitute legal advice. You must speak with an attorney to discuss your individual case.
You will need to file for a change of status from L-1A to B-2, on Form I-539. Cannot change to "ESTA"; can only initially enter the US on ESTA.
