I was planning to attend the next available ceremony to get the certificate then apply for British passport. I got the impression that 'Once you have a British passport you must use this to enter the UK.'
Now I may need to visit an elderly family member overseas shortly. It's not that they are serious ill or dying but to better use my scheduled time off. As it may be too late if I only get my British passport up-to-2 months after application. I'm wondering:
1: If I should travel with my original passport (Taiwanese) plus current BRP, and attend the ceremony after I return to the UK (I know it should be within 3 months of the approval). Will the custom question the situation and refuse the entry to the UK?
2: I can still attend the ceremony to get the certificate first then travel overseas with my Taiwanese passport and BRP. Apply for British passport when I return to the UK (But I thought once I get the citizenship certificate my BRP will be invalid then I won't have valid visa to enter the UK, it's also risky to carry citizenship certificate with me while traveling)
I had tried to find the relevant information in the forum but no luck, any insights and suggestions are appreciated!
