The maximum limit for that is $2000 but It depends upon your passport in the sense that If you have stamp of some dollars in your passport that some travel agencies stamp in your passport the amount which you paid while buying t$icket, then you cannot carry cash $2000. You are legally allowed to carry the rest amount from $2000. Its risky it TIA if you were checked. But if you are already familiar with TIA, hardly they check. So, its no proble. If you were checked and found more then that then it will be tragedy...... you have to loose it. So, it depends upon you: u want to take risk or not
