(Note: If I receive a lot of calls, there may be a slight delay for the posting of your documents.)
I suddenly have the urge to call Ms. Yin a bunch of times...
anyways, we can make a group after EVERYONE gets results.
makkuro,
congrats, does everything feel lighter now?
fiveonefive,
I don't have exact answers, but I will try to give you some info.
jumping into masters:
It's much more common to enter as a research student, so everyone is quite use to that. So jumping into the masters course is much more difficult I think. The following is just my assumption: First you would have to be accepted into the universities masters course before you even apply for the scholarship. Then when applying, you explain to them that you have already have acceptance into the masters course. Finally, if you past the first round, MEXT will handle the rest. It seems like there is a lot of trouble using this route.
1. taking the exam/interview and waiting for results
2. maybe you will only be able to apply to 1 univ.
3. risk not getting the scholarship even though you were accepted into the univ.
we really don't have exact answers here, please ask your embassy.
research proposal:
I think kouki is right, it is a "proposal". I think you are on the right track and you can also tell them that you have already been accepted into a univerisity.
