How can I move to Spain from the usa and be a citizen of spain and renounce my us citizen ship?

How do you do that? How long does that take to be a citizen? How much does that cost?
In spain is there good jobs like in the usa? In spain do they have welfare and foodstamps like in the usa? How much money do they give you in welfare there?
If you become a citizen of spain is that to be permanent if you want?
In spain is there many americans that live there? What about people form other countries?

You should get a hold of the Embassy of Spain and ask how you should go about doing this.

If it's like the US, you have to have a sponsor from that country to live there, get a resident visa, which is good for 1 year, in the US (don't know Spain), who will be responsible for your behavior while you are in that country.

Denouncing your US citizenship is another thing altogether.
Before you do this, make sure it's what YOU want. You can hold dual citizenships, which is better. But once you denounce your US, you are out of luck. Think long and hard about that one.

Good luck.

Think you should get a visa and visit Spain, Italy, France and the rest of Europoe before becoming a citzen there. See what it is you looking for first hand.

Don't give up your US citizenship! OMG people from Europe come here every day and want citizenship in the USA. You ask if Spain has good jobs like the US? and welfare? It doesn't sound like you plan on working much once you get there. Why not just give it a trial run? For a six months or a year. I'm sure you can get a work visa for Spain. Think twice and then think again before giving up your citizenship in the US.
