(1)Who is H1, you or your LD?
(2)Who is J2, you mentioned "H4脫離J2 (EAD過期)", not sure where did the "J2" come from?
(3)You said "於半年前申請了一個公司", did you work for someone else's company, or did you run your own company?
(4)"有現金和支票存入個人帳戶", is this from payroll? W2 or 1099?
without these clarification, can't say.
