Spouse Visa Applied and Waiting for Son B.P

[shaikh1234]

Hi there

Recently I applied my wife and one son Spouse Visa Application and I also waiting for my one son who born after my British citizenship. I applied his British passport from my home country since march 2020 and still his application is pending and several time I contacted with HMPO regarding his Passport application and they said as usual that still in process while I had been attended skype interview on 19 Dec 2020.

My question is that if my family get visa so what option is available for my this son who is waiting for his british passport?

can I also get any travel documents from Foreign and commonwealth development authority for my this child to travel to UK?
