My wife is a Russian national. I am a Norwegian national.
We lived in Sweden for 10 months. During that stay she got a residence card (EEA family member) and a biometric Swedish ID card from the Swedish Tax Authority.
We moved to Norway two months ago. She has applied for a new residence card (EEA family member) from Norway through the Surinder Singh route. She has a letter from the Norwegian police saying she has applied, and a document from the Norwegian Tax Agency (D-number). Norway may take several months to issue her the residence card, but she has the right to stay and work in Norway while waiting for the card.
We are considering a short holiday trip to Poland for four days. My guess is that it should be no problem since it is a flight within Schengen and she is here legally after all. However, I am unsure about some things.
What ID should she use at the gate, etc? I am thinking it might be better to use the Swedish biometric ID card, since a Russian passport without a valid visa may appear to mean she is in Schengen illegally, and cause trouble. I suppose the EU residence card from Sweden may now be void since we already moved from Sweden, although she still has it.
Also, I guess as an EEA family member she has freedom of movement in all of the EU when she travels with me, even on holiday?
We are planning to fly from Torp Airport (TRF) to Gdansk Airport (GDN).
How likely is it that she will be fine on her trip? How can we minimize the risk of any inconveniences?
