Good for your neighbors, they should be very proud. How about a fresh all-American apple pie or a book on American history as a gift? If you want to bring a plant, put a little American flag in it. Have fun at the party.

Thanks, dian. Great ideas, but the party was last night and I just saw it this a.m. I ended up going with a gift basket with some food items wrapped in decorative bags that said such things as "Call it Home" and wrapped in a ribbon with a little key hanging from it. Then a small photo album with a personalized front cover with a green alien graphic on it, and the alien was holding a sign and inside the sign read the family's name. Then "Celebating with our Resident Aliens" was displayed on the front and then the celebration date. Other food items also were in the basket. It was really cute, and I'm glad I decided against the bottle of wine. That was the standard gift. Nice but I wanted to put a little more thought into the gift.
