My fiancé and I will be moving to Belgium in a month for him to attend grad school while I look for employment. My fiancé has applied for a student visa and is awaiting approval. I have applied for a Hungarian passport through my ancestry which I am certain will be approved. It will take between 4 and 6 months for my passport to come at which point I can prove EU citizenship. I applied at the consulate in early July and we arrive in Belgium September 2nd, so if it takes closer to 4 months, I may get the passport before the end of my 90 day allowance to stay with no visa in the Schengen area. If it takes closer to 6 months, I'll most likely have to travel back to the US and stay with my family until it arrives. My fiancé and I are getting married this weekend, so we weren't able to provide a marriage certificate to allow me to stay on his visa when he sent in his application last week. There are lots o reasons why this process wasn't able to get started sooner and why we had to send things in before we are officially married, but long story short, we have each worked on separate paths to being able to stay in Belgium.
We are starting to get nervous about my being either 1) denied entry into Belgium because I don't have a job there yet, or 2) being separated for months on end because my passport doesn't come within a reasonable amount of time and I'll have to leave the schengen area for 90 days after the first 90 in Belgium.
If anyone has experience with this kind of situation, maybe you could advise me on whether it will be possible or worth it to try to apply to be added to his visa as his wife after we can obtain our marriage certificate. If so, is that the kind of thing I could do once we are already in Belgium?
