All Asian Countries are the same, they do not want to be with a SP / MPA over 25 tops. Literally 28 year old is one year off GILF to them, they are serious about it. The SP / MPA can lie just like here but quickly becomes difficult - more on why later, usually they have to move or go into a place with a lot of foreigners. If they can bank enough (you need assets to immigrate or get work visa, education visa, not just arrive poor and say "let me in."
Unless you are buying an Asian MPA a car, house, condo, or some serious simp service, I can't see them letting you know their real age / ID, 98% they will lie / fake ID, etc. They came here looking to achieve early retirement goals, telling you her real age / name does nothing towards that goal. If you were not their customer golden goose, they would be stepping on your back to get ahead toward their goal, not stepping on your back for a massage.
There is a way to get near exact age of a person without them realizing it even, and extremely difficult to lie, or at least you would learn how much they are likely lying. I used it, and thought I invented / created the tool, and then an Asian used it on me and I'm like wtf probably everyone in Asia knows the trick. The thing is this likely worked for me because I am Caucasian of course, used it against Asian, and I'm guessing they did not expect I would know their little secret. Let's see if one of our Asian members would like to chime in here and explain, I'm horrible at trying to explain exactly how it works, or I should say how to pull it off in a reasonably short period of time. When I first "accidentally invented" it (my version), I did it over months and most people want to use it within 30 minutes.
Before even thinking about it, you would need to have the ability to not only speak, but actually hold a conversation with the MPA you are attempting to get age of. I know many guys are not interested in conversation at all and have no skill whatsoever speaking with someone to any extent (even asking name), of someone with limited English. This will not be, or work for you.
