OK, so I've submitted my EOI now, but after having read some more forum posts I am worried it's just going to be sent straight back.
When I filled in the online EOI we couldn't find my wife's birth certificate, but the field wasn't "madatory" so I didn't worry about it. Now I keep reading that you HAVE to supply birth certificates etc (even though a passport should supercede it).
Will my EOI get bounced because I didn't put any details down about my wife's cert?

Similarly with Tax Number (not even sure what that is. Nothing I have from the tax office has any other number than our NI numbers), I left that blank too as it wasn't down as mandatory either.
