How long can I stay in EU and still travel to Russia, US passport holder?

Question

I am a US Passport Holder and am staying in Spain at the moment. I have a job in Russia that starts Mid September. But I understand I must leave the EU after 90 days on a travel visa. Can I just go to another EU country and stay for a few weeks there then go on to Russia. My passport says I must leave spain Aug 25th and my job doesn't start till Mid September. Can I go to Germany, France, Italy or England in between?

Answer 1

UK is not in Schengen, so u can come to UK on 25th August (or a week earlier) & stay here for few weeks & then go to Russia.

Answer 2

If I am not mistaken, you have Shengen visa for Spain. And it means, that you can stay in Spain or any other country of Shengen till visa expires. There may be problems if you stay longer in any country of EU. But I am not quite sure, so check this up.)
