Here in Egypt, the maximum depth for recreational diving is 30m, unless you have deep diver (40m) or tec training. It's par of the reason the cards exist, after all.
Actually the maximum depth limit is 40m, it was even on the CDWS test in 2009.
Don't forget PADI certifies Advanced to 30m. This is not the same for all agencies.
BSAC sports diver is 35m
CMAS 3 star: 40m
