Naturalized citizen with expiring GNIB card due to travel in October

[kelzer]

My partner has just received her Irish Naturalization certificate last week. We are due to travel to Greece in Sept and Spain in early October but her GNIB residence card expires a few days before our Spain trip. Since she has to send her original Mexican passport in order to apply for a first time Irish passport, she won't get her new passport before we travel to Spain. Will showing her naturalization certificate at Dublin immigration be sufficient, or what could her options be? We don't want to cancel our Spain trip.

I suspect your partner will be very likely to be denied boarding by airlines flying back to Ireland if they cannot produce a valid IRP and/or a visa to enter the country. I think it could be a good idea to try to get a re-entry visa before that trip.

Also forgot to mention boarding the return flight to Ireland with an expired GNIB card but showing the Naturalization cert. Would there be an issue here?

Where and how can we apply for a re-entry visa?

But your partner doesn't need it. Mexican citizens can go to Ireland visa free -> they can get on the plane as if they're going for tourism and explain the situation on the Irish border.

Yes, if your partner was a visa required national.
Airlines have no idea what is naturalization certificate and how to verify it. For them, acceptable travel documents are visa/IRP/(elegible) passport.
