1,現在我是不是H4在非法工作了?
-Yes if your status is effective (check the H4 effective date from the H4 approval notice.
2, 3月底我就辭職了,如果是非法打工的話也就20天,會有多嚴重的後果?會給我以後申請綠卡或者回國簽證帶來麻煩嗎?
-Because you violated the H4 status rule, your H4 status is invalid and that means you are unlawyfully present at this point. Unlawyful presence for several weeks does not affect your anything if USCIS does not catch you and deport you. But the problem is that if you continue to stay in U.S., your unlawful presence will increase and whne it reaches 180 days, you will be big trouble. So, you had better go out of U.S. to get an H4 visa to come back and thus, your unlawyful presence record will be removed auto matically.
3,我曾谘詢過律師,有的律師說我在非法打工,
-I agree with this lawyer
有的說因為我H1B的I-94還在有效期內,所以沒有任何問題,請問哪個說的對,
-I do not agree with this lawyer.
