Personally, I like the Fuji Bldg and the Phoenix Bldg gets an honorable mention.  Both are in CWB.

I believe all of the walkups are legal as long as there is no more than one woman per room. I think Coronet Court is being watched carefully by law enforcement because most of the hot ones there are working on 7 day visas. (Which I believe is illegal.) The john should be okay, but who the heck wants to get caught up in a raid

OK class, pay attention now ...

the BUILDINGS are legal
PUNTING is legal
SELLING SEX FOR MONEY is legal

but anyone doing any work in Hong Kong without a Work Visa or Residence Permit - paid or unpaid - faces a possible jail term.  

Most of the girls working in their own appartment - aka walkup aka 141 - are locals and are totally legal (from their point of view).  

But the Immigration Department only issues a Work Visa to a foreigner if a) an employer will sponsor the application and b) there is reasonable proof that a local is unable to provide the same services.  Even if b) is the case - i.e. a girl who can actually offer something a local girl can't - she would fall foul of the prostitution laws as a result of a) because she cannot (legally) have an employer or agent for doing sex work and therefore cannot have a sponsor.  So she can't get a work visa for sex work.  

This is why if you look around you'll find some girls who come to Hong Kong don't trouble to get a work visa ... hoping to make a quick buck off a quick fuck without getting caught ...

I can just see it now:

Knock, knock, Oh Mr. Wong you're home, hmm is your daughter working tobight?

So which area has the younger ones and can speak english? Most of them have blur faces.

Because all the young girls i saw in a building at Wan Chai looked like PRC WGs, it means all of them are illegal.
does the raid often happen?

Tsim Sha Tsui - Blk. B, Champagne Court, 16 Kimberley Rd.
Causeway Bay - Fuji Bldg., 381-383 Lockhart Rd
that is the most famous in HK

Do you know which one has younger girls? Got pictures of those locations? relative to mTR?

Pictures and maps are in the ads.

u can search some report in this forum

80 Tung Choi Street! Entrance is well hidden behind the market stalls of Mong Kok, and the girls are quite decent too! Only downside is there are many times when all the girls in that building are occupied, and the lines can sometimes get ridiculous.
