I will be soon traveling to Pakistan from UK.
I would like to take £8000 with me, based on rules anything below 10,000 euros doesn't need to be declared.
How can I keep documentation other then bank withdrawal of taking this money with me on my holiday? I am a Pakistani national and but will soon be British too in coming years, if it's any relevant. In past I did took money but I have no proof of taking money to PK other than bank withdrawal.
Of course money is legal coming from my salary, but what are outcomes if I declare it (not sure how though)
Edit
Why I want to travel with money and send it through banks etc ?
Because I might need same money back to UK so I don't want to convert currency twice or even once to avoid low rates I will get from banks here sometimes with extra fees.
Also I get good convert rates in local market then sending online or through banks.
