dwayne,
from memory (it has been a while) yes they do, as long as the work is certified by a guy that hold a valid license for the work
ie you do the work, the licensed individual certifies in the aircraft logbooks, that licensed individual then also certifies your logbook for doing the work,
from memory there is a section at the front that he needs to fill in, kind of a signature register with his details, name, license number etc
i have done this in the past with australians certifying my log book and had no problems
