ok a long complicated one for anyone who knows about these things and has loads of time on their hands

We lived in Geneva for the past 7 years, and my daughter was half-way thru her passport application when we had to relocate for 2 years (and will be returning to Gva after)
Her passport application was ''put on hold'' by the authorities provided she returns within 3 years, which she will do for her further studies (and hopefully life !)
Ofcourse once we left Gva we ''lost'' our B permits (provided by the Co.), which were ''frozen'' by the authorities for 4 years.
Now the question is - when my daughter returns to Gva next year (without us) to study, must she apply for a Swiss student visa in the country where we are presently residing ? Or would there be some other ''permit'' available to her due to her previous long-term residence there and pending passport application ?
We will follow on about 6 or 8 months after her, and ofcourse at that point we will all have B permits again.. so it is the initial period while she is at uni that is of concern to me.
Thanks to anyone taking the time to read this and helping me !
