My adviser threatens to kick me out if I am not to be a full time student Background: I have been in the Phd Program since fall 2010, I have made great academic progress (two papers published in journals). From the 4th semester (spring, 2012), I have started working in a company and still a part time student in school. Till now, I am still keeping doing research and publish another paper and one conference paper. As I have finished all coursework requirement (72 semester hours, I transfer some credits from MS), I plan to work in the company and be a part time student to finish the degree. 

From last month, my adviser kept asked what's my plan. I told him I will make my decision in mid-July as I can know my H1b working visa is approved or not. He send me another email ( I post here for information). My impression is he is threatening me...

Any suggestion? Again, it's difficult to look for a job for international students in such economics. I hope I can work and study as a part time student to finish the degree.
It is completely inappropriate for an advisor to send an email like that. The email makes it clear that this is an advisor that you should steer clear of. At a minimum a change in advisor is required. I would also approach the department head about the email. Faculty need to know that they need to behave better.
