U.S.travel: would you like give me some suggestion?

Welcome to the U.S.A !! Be sure to visit as many places as possible. There are several places of national and international importance which everyone loves to see... Also, carry some warm clothing. Winter in northern USA can be trying :(

Depends on what type of weather you like... Next month would be October... Up north states like N.Y. & Maine are really pretty... Ok, not in N.Y. city but outter skirts of it... I live in P.A. & there's not much here... If you like warmer weather, Florida is always good...

I wonder which airport in the USA you will be flying it to. Popular gateways are Boston, New York, Miami, Los Angeles, San Francisco and Seattle. Honolulu is in Hawaii. I have been to California three times and to Hawaii once. There is a lot to do in Los Angeles like Disneyland, Beverley Hills, Hollywood and the Universal Studios. I liked it in Santa Barbara and San Francisco even more. If I went back to the USA I would like to visit Boston, Cape Cod and New York. It would be lovely to go to the Florida Keys. The USA is a large country with very much worth seeing. I traveled around by train mostly. I suggest you take a travel guide book with you and get travel insurance. Good luck planning your trip.

What part of american are you coming to? because american has a lot of things to offer but it cant all be done in 3 weeks.
