Thank you in advance for taking the time to answer my questions.

I'm an American citizen (USA) married to a Spaniard and I have legal Spanish residence. I'm not planning to move back to the US, but I'm not sure of the advantages and disadvantages of getting Spanish citizenship...
We've been married for 6 years and live in Spain full time.
I currently go back to the US for one month every year to visit my family, and I have a bank account, some investments (stocks and bonds) but no real estate there.
I don't have any retirement income in the USA.
I own part of a small farm, with my husband here in Spain, and a car, etc...Although his portion of the property falls under Catalan marriage law, so it would go mostly to his family when he dies, unless he has a will directing otherwise.
I don't have any political reasons to want to be either Spanish OR American...
Thanks again for your consideration of these questions.
Sincerely, J. Ruoss
