thanks for the answer swisspea, It is good to know it doesn't take as long as in the UK where the EEA2 permit takes at least 6 months.
It is a very good idea and of course I would do it to contact the Swiss consulate/embassy in UK. (as we live here)
I just wanted to know in advance what to expect without going those places
But maybe you are right and I should not speculate with comments here and go directly to the official source of information.
Thanks again, and If anybody else have something to add I will truly appreciate it.
Regards!
