American citizen traveling in non-Schengen country on D visa

I am an American citizen with a +1 Transit Schengen visa valid until the 29th of November 2007. I do not have my carte de sejour yet, but I want to travel to Budapest, Hungary (which is not a Schengen country) during the first weekend of October.

As an American citizen, I do not need a visa to enter into Hungary. However, would it complicate matters if I do not yet have the carte de sejour? In other words, would I have any problems getting back into France from Hungary?

Thanks,

Christine

Your French long stay visa is valid for multiple entries during three months. So, during the validity of your visa, you can reenter France.

And anyway, as an American citizen, you could enter France without a visa. So I do not think you would encounter any problem.
