How would a second passport help you with this requirement by the
French consulate?
Every applicant must apply in person and must make an appointment on our website. No exceptions. Fingerprints and a photograph must be taken in our premises in Los Angeles.
And their first appointment in LA now is for June 29.
You may want to contact the French consulate in HK to see if they will exceptionally process you there. Perhaps your summer residency will be enough for them. They are a lot easier to get a hold of than LA, and they have appointments available for any day, even as early as tomorrow.
