Visa approved but not issued.

[kiny 0]

My husband had his interview on feb 21st, the visa was approved and they told us it's going to be isssued the following week but it's been five weeks now and no visa as of yet. Contacted the montreal consulate a couple of times and all they tell us is to wait and if i ask them is the visa in security clearance or something they just say that we can't disclose that info to u...then yest I called the DOS as advised by someone here on the forums and she told me right away that your visa is pending security clearance and it's in AP. I asked if it was something common or something I should be concerned about, she said it's pretty common and our case looks good so we should be done soon...but since my husband was born in Pakistan i am taking it with a grain of salt....any guesses if we'll get it within three months...I've been hearing stories from people that they had to wait for years if that's the case then i'll have to leave my job and move to Canada to be with my husband...normally how long do security clearances take if the case is good...do u think it's agood idea to ask them next time who's doing the checks meaning the FBI or the consulate? Aren't they supposed to give us a pink slip or say something during the interview if the visa is going to be in checks for a long time? they never said anything ot my husband.
