Things allowed and not allowed in US airport?

Question

Im a first time traveller to USA. I would like to know how many kilos am i allowed to bring. Most importantly, what are the things that are allowed and NOT allowed to bring to the USA? Is it true that some imitation bags and other things are also prohibited?

Answer 1

I don't believe there's a weight limit for carry-on luggage, but checked luggage varies by air carrier.  Most of them limit you to 50 pounds per checked luggage.  They will permit more, but they will charge you an arm and a leg.

Go here for lists of permitted and prohibited items:

Answer 2
