Hello. I arrive on SQ25 from JFK (B46A, not clean?) and transfer to an intra-Schengen flight out of B.
I understand that I'll likely need to go through security, but can I avoid passport control and remain in the non-Schengen area to access the AC lounge? Obviously I'll have to go through immigration eventually, but I'd rather not be forced into the Schengen area immediately.
