我以在美工作4年，H1B还剩2年。请问现在可以换工作吗？有没有规定说H1B还有一定时间过期时，就不可以再办了？
I've worked in the United States for 4 years and still got 2 years on my H1B visa. Can I get another job and a different H1B? is there any rules that says new visas won't be granted if your H1B is expiring in a certain amount of time? I ask this because it's impossible to enter the united states if your passport will expire in less than six months. I wonder if there's similar regulation on H1Bs.
Thank you!
