we had the same problem..me and my husband was block-listed by the CID..at first we don't know y? but after few weeks we knew what the reason behind...it's all because I had delivered my baby in HAMAD and HMC reported me to the police that I am still single in their record, but im already married...CID wants me to transfer my IQAMA automatically under my husband sponsorship...my husband's iqama couldn't renew as long as my visa is not approved...

it was a long process..but we are almost done now...we had too much patience to dealt with this kind of situation :)
