Am a zen mahayana advocate here, so female monastics are
perfectly fine imho.
Still, whether becoming a nun is a good choice or otherwise is a
matter of karmic conditioning, so for instance in another post by
the TS awhile back your friend Karin is possibly in such and such a
circumstance in Vietnam because of her own karmic possibilities.

buddhists may prefer wishing one another well, at 22 years of age
if a woman or even a man wants to become a nun in South East Asia
then please, anything but being caught by the government because
she will possibly be coming back and becoming a lay person against
her wishes. If you want to be a nun whether for the fun of it or
otherwise, and if you can speak Chinese i.e. Mandarin, as long as
it's a Chinese-predominant state or province you are in, that is a
good place for your monastic training and suffering.
Being honest, if a woman has the conviction in being a nun,
sincerely it does sound like a better idea imho than some girls
that enrol in universities then having to work as social escorts to
pay their tertiary fees. Go talk to Venerable Kwang Sheng or Chuan
Guan about it at Bright Hill monastery if it fits
your bill.
