I am planning to carry 5 mobile phones with me to US from India. All the phones are new but unpacked. I have laptop too. Am planning to carry evrything in my hand luggage. Is that fine? Or will this put me into trouble?
I believe it's perfectly fine. Just declare them as you enter (on any form you might have to fill in and when talking to a customs officer) and they will tell you if you need to pay any tax or duty. As long as you are upfront and proactive, you will not get in trouble. Bringing any invoice or receipt you have is also a good idea.
