Oh, congratulation! Do you have any experience in IT security? I assume you have if you can get CISSP. Before going into it, I have to say that I did not migrate here via working visa, so my case might not be 100% applicable to yours, but the fact is that companies here do need IT security people. Surely they would give priority with someone who has visa already but they would not hesitate to hire you if your background can fit them. I think the first step is to polish your resume and LinkedIn page. Resume in US is in many ways different from the one in HK, I took 6 months to rewrite my resume and got response from agents and employers. For example, their resume must keep in 1 page, and you have to show your achievement and contributions in your past job. The agents like Indeed and Monster would scan resume using AI, so people without the "required" keyword would not even be selected. LinkedIn is the most effective way to get a job in the State, HR are connected via social networks. I can show you more if you are interested.
