BNO　國藉問題

梗係用得,我用過去台灣,不過...你個bno仲未過期咩?我都算好遲先換,都過咗啦,check清楚先好d,旅行證件,好多地方都要你仲有6個月有效期架,最好就係問旅行社啦~~用bno,你只不過係海外公民,就算你响外地有事,都係去中國大使館架,就算你要移民去英國一樣要申請,因為你唔係公民,而係海外公民,所以你唔係英籍,而係中國籍

You are considered Chinese citizen by HK gov even if you hold BN(O). The HK gov after 1997 and China gov do not recognize BN(O).

When you use your BN(O) passport to goto Taiwan, you can write BN(O) as Nationality on the Taiwan entry form, because Taiwan recognise BN(O).
