Hello, I was wondering if anyone could help me in answering some questions about moving to Spain, I am a US born Mexican who speaks spanish fluently, I have been considering moving to Spain specifically Madrid, what I wanted to know was if finding a job would be difficult,  and if it would be easier if I try and get a visa and then get a working permit seeing as I have friends in Madrid.
I dont know what the cost of living is in Spain is so knowing that would help in job hunting just to start planning ahead. Thanks in advance
