"Registrada" is NOT the same as Admitida. If you look in the manual under "glossary of terms" at the end, you'll see it basically means nothing. My best guess is that you're on your way to being Admitida if you're "registrada." At least, that was my experience.
Oh, you're right! I just looked at the "Glossary of terms" in the Program Manual, and "registrada" is a step inbetween "inscrita" and "admitida." I assume though, that because of the timing, it probably means that they've received all my documents but haven't given them approval yet. So... I will try to be patient.
For anyone who is curious about status meanings and doesn't want to bother going to the program manual, I thought I'd cut and paste the glossary. I'll start with "inscrita" since I think all of us have gotten to that stage at this point:
Inscrita: ONLINE APPLICATION SUBMITTED
Registrada: Paper application registered, has no real significance in the process.
Admitida: Application complete, application has been processed and has all required hard copy documents, eligible for assignment.
Adjudicada: Assigned. A regional placement offer has been assigned and made to the candidate.
Reserva: Reserve, wait list. The auxiliares norteamericanos program does not make use of this status; rather your application will stay in “admitida” status until we reach your application number.
Aceptada: Placement offer has been accepted by the candidate. The candidate has committed to participating for that region.
Renuncia: Decline of placement offer. The candidate is no longer eligible for any placement for the upcoming academic year.
Sin plaza: No placement. Not used.
Excluida: Excluded. Occasionally used to remove your application from the program. Usually if the candidate no longer wishes to be considered before assignments have been made.
Excluida global: Excluded from all vacancies for any programs offered that term.
Registro excluido: application excluded.
Funny that "Abierto -- Tramitación" is not on the list of definitions since that what my status currently is when I log into Profex. I am going to guess that it's meaningless and that I'm actually in the "Registrada" phase..
