Permanent residency worries

Guys,
My wife applied for permanent residence after 5 years on stamp 4 EUFAM Visa.She is married to me EU citizen.She got temporary extension for 10 months(apparently because of Covid19 backlog) with a view that they going to bring decision on permanent residency after that period expires.

Unfortunately my circumstances changed for bad as I was diagnosed with serious health condition and I shouldn't be working as per doctor's advice.Im currently on PUP payment and worried that if I go on illness benefit after they stop PUP payment,her visa renewal might be affected.

What's your take on my situation?

Sorry to hear about your health.

My understanding is Illness benefit is a taxable income that is based on your PRSI and so its won't be treated as a "benifit" benefit as its your entitlement coz of your PRSI contribution.

Anyone else feel free to correct me if I am wrong.

I hope it helps n all goes well.
