This was the 2nd time of using them - first for a fiancée visa and then an extended 'leave to remain'. I was full of praise for the first job ( thanks Abimbola in Manchester) but the second time, the job was relegated to an assistant and there were a high number of errors, omissions such as mis-spelling of my partner's surname which was time consuming & frustrating when documents had to be perfect for Immigration to approve ..I do not think the high cost of the form-filling by IAS can be justified when it created more work for me in double-checking and raising queries.
