Ouu,, I've a question here again...
Well, i just renewed my passport after i got the visa. Initially i thought they can bind both the old & new passport. Who knows they told me i have to transfer the UK Visa Stamp on to the new one. Do you guys think the officer ll kindly transfer it for me? I'm worried now.
The safest thing to do is to contact the UK Borders Agency to get advice. I know a few people who went through this, and they were told to carry both their old and new passports, and present both when entering the UK.
I have experienced this personally. I was told to carry both passports and have since re-entered the UK seven times and never had any problems.
