Hi Grooenmamba
To obtain stamp 4 you need numerous documents. I will list them below:
Being self employed- 6 months bank statements or invoices
Being employed- Job contract, two payslips
tax credit certificate or p60
PRTB ( registered by the landlord)
Tenancy agreement
Bills in your name and the spouses
Lastly, you need to submit all these documents along with the EU 1 application form (found on the INIS website) it will take about 4 weeks thats how long it took my husbands. Then you will receive a letter and you tke that to the gardai, burgh quay city centre and they will give yr husband a stamp 4 for 6 months until they process the stamp4EUFAM.
Hope this helps
