Thank you!Yes, you are. You can apply directly for a British passport.
You need the following to apply:
Hope this helps.
- your long-form birth certificate listing your parent(s) names (both is better, but mother will do)
- your parents' British birth certificates
- your parents' marriage certificate.
Thanks Riley. It confirms as I thought. Yes he was born after their marriage. But can I apply online in the Uk as his representationor does he have to apply over there. I read you have to apply overseas at the British consulate and there is no online procedure like there is on the Uk. Just conscience that their level of English is poor and it’s easier for me to do it as I am born and bred in the Uk.Provided your step-brother was born after the date of marriage - as it sounds like - he can apply directly for a passport.
The naturalization certificate and passport for your father and the birth certificate with your father's name are good. A marriage certificate for your father and your step-mother is the last thing you need.
Apply online, as you said. If they want any more documents, they'll let you know.
