[amjadleeds]

Hi everyone,

my application for ILR is under process , I applied for my family through solicitor on FLR O form four weeks ago, still we havn't received any letter. My application been delivered to HO on 15th March, through my solicitor.
My question I want to call them to inquiry about Acknowledgement, can I call them if application was send through solicitor, second on which number I have to call for this enquiry.
Other i made bank draft for payment so my account debit as i made bank draft so cant check via they received payment.
Any one have same sort of experience not received acknowledgement letter after application date four week.

Your views/ advice will be great.

Regards
