Going to be visiting soon and looking for a nice K girl or other compliant asian FS option. Best if on the east side or near downtown. Looking for agencies that I cAn get in at and maybe see a couple girls while I'm there.

Many of the frequent posters there are LA guys.  You will learn everything you need to know about how impossible it is for visiting guys to get into the LA Kgirl scene unless they are willing to give up their employment information for screening purposes.  

can't get into K-girls scene for visitor?

Nope.  
You need k-girl references. There lies the conundrum.

Thanks. Ok then best bets for FS AMPs or independent asian girls?

are Mia Hug and Parker South in LA, or Lisa Lang in SD.  All three well-reviewed on TER.
