I have worked in L1 B visa for 2 years in US. Due to disagreements with employer, I have resigned from my job. My offer letter said 4 weeks under notice period which I will be giving. I have mentioned that my resignation should be effective immediately meaning my notice period should start. But I have not received any acceptance of resignation till now. Can they deny my resignation? I still hope this ends in a better way. But just wanted to know my legal options.
