1. I am currently on an L-1 visa but I am thinking of resigning my job. I have an Australian passport, so if I do so could I just change my status to the Visa Waiver Program or would I need to physically exit and re-enter the country? 2. If I subsequently wish to stay longer than 90 days under the visa waiver program, am I able to simply exit and re-enter the country to restart the 90 day period?
1. You will have to exit and reenter OR apply for a change of status to USCIS.
2. This is not guaranteed to work. CBP can decline second entry if they wish.
