Passport Application Query !!!

Hi All
Am trying to fill my First adult British Passport.Am stuck On ''Family Details Section'' My Parents dont have Surname (Last Name).So What can i fill in Last Name Column? Any idea Please guys?

Can it be left Blank and move to next page if it allows me or can i Write ''NOT APPLICABLE'' in Last Name column?

Presumably you naturalised so your parents' details are no relevant. You can fill in details or n/a until the system lets you move on. There are many pathways to British citizenship but only one passport system.

Hello Guys
I applied for my First British Passport on 4th August and after Submitting it says it will take 10 weeks. I thought it was 6 weeks last months Is there anybody who applied recently getting same message?

10 weeks is the standard HMPO target - just like UKVI have 6 months target for natura;isation.
Most applications seem to be much faster than this though of course now more people applying for passports.
Best you follow the passport timelines on this forum.
