Hey I'm so sorry to hear that ..but I think when the embassy sends any of the request letter for something like Pcc, medical or any additional documents and it gives us a specific time limit to submit ...in the end of the request letter..there's always one line mentioned...we r execting these things from u within 30/45/60 days and If we do not get,ur application can be refused on what info we already have !!!
This is not exactly what they write but similar to that is always there..
I think they sent u some request letter about anything additional ..u guys misses it and they didn't get what they asked for and they refused ur application ..do u know exactly what happened ? Did they state the reason of refusal ?
Try to find out what they refused and discuss it freely with forum members ..I'm telling u they would help u get out of this IA..
