My situation is kind of unique so I have yet to find any answers that apply to it. I was wondering if anyone is familiar enough (or experienced something similar) with this to help me out.

I am a U.S. citizen living and working on a Long Term Visa and Work Permit in the Czech Republic. I intend to marry my fiance in a couple weeks (legal paperwork and all) in his embassy here in CZ. He is a Portuguese citizen, and EU passport holder.

My question is, my visa will expire in April, so how will being married affect my visa status? Should I apply for some kind of residence permit based on my spousal status, and if I intend to work I would have to process another work permit? My main concern is being able to stay here in Europe after my visa expires. Since my soon to be spouse is, and will be working, this should ensure my stay, and not require us to present any proof of financial funds for support, right?

Also, what happens if we intend to move to another EU member state after we are married, such as Greece. Should I begin processing my residence permit (or whatever is required of a spouse of a working EU citizen) for Greece, or secure my visa status in CZ first? My visa expires in April, and we would probably move around that time, so my concern is being legal in between.

I found this which seems pretty clear that I have the right to be bound to my spouse and can not be deported or anything due to expiring visas, only to announce my presence in any EU country and receive some kind of residence permit.

Also, how does this all apply to Schengen? Or when it comes to EU law and marriage Schengen doesn't really apply?

Sorry that was so long, thanks for any help!
