Was self employed, on DA for 18 mths, have applied for IP, how long does process take

I have been on DA for about 18 months, I was self employed, I now have enough PRSI A type credits. I applied for IP, and Social Welfare sent me the GP Form, Which the GP filled in, I also gave them permission to contact my medical consultants. That was about 3 weeks ago. Does any one know how long the process takes ?

Just to clarify for members that might not be familiar with abbreviations what does IP stand for?

Thanks

Thanks aj, have just modified my post

Have you checked with SW that you have sufficient A type credits awarded to you as I note you were self-employed prior to your DA. and therefore paying class S contribution

The records dept. in Co. Clare found 43 A Class Contributions in 2008, plus 18 in 2009.as I was only an employee of the company at that stage. I have been geting credits at Type A on DA.

Normally they just send you a letter to say you do not qualify for IP, due to lack of A type credits

On this occasion they requested a medical report, which is normally the second stage, after confirmation of PRSI rule. As I am on DA anyway, and receiving the allowance, I am not to concerned. I was just wondering how long the process takes

I have seen them do the medical first and sort out the PRSI requirements later.
