Greetings from a Fellow Texan..also from Dallas
Firstly you cannot look for work/ work here without a work visa. I have checked this with the HK Immigration recently and they have confirmed this. The officers urged us to report people who sought work with us with tourist visas. I don't think they enforce it but its best to be aware of this.
Most landlords will ask you for a HKID or they will not rent you any premises.
You might want to research your job prospects here thoroughly as it is not that easy to find work unless you speak Cantonese. Either way I wish you the best and hope to see you more active on the forums.
