Can anybody give me advice on moving to Spain from the US?

well girl, the spanish economy is cooling down , due to the burst in the local housing bubble and certainly the spanish economy is going to be hurt by the global credit crunch which is currently under process. I ASSUME You married an spaniard or you have european spanish background, otherwise you 'll face huge troubles to open your business. the spanish economy is not so flexible like the U.S. economy, not to mention the taxes, THE LABOR LAWS are quite different compared to U.S. laws. another data which i consider importan is: Spain has the lowest birth rate in the world, so for SOME REASON the people can't afford having children I know i know in the majority of the industrialized world the birth rate is low but Among spaniards this is particulary acute, so you'd better think twice about moving to spain. if you have papers to work in spain , why don't you take an exploratory trip and try to get a job teching english, once there you'll meet locals and have all the info you want from first hand and you'll be able to see what's the best option. I know there is a shortage of english teachers, and you may take advantage of it ,anyways that's up to you. good luck!.
