Hi guys
My husband and i went to infopass today,first was my appointment,officer was surprised about delay on my case and he said there is a request for interview on my file since September 27/2016 which i don't know what does it mean?then he said i should sit until he can find out what is heppening?after 10 minutes he called my name and told me because my case is digitalized he does not know who is reviewing my case and he sent an email to his supervisor and waiting for her answer,i should go back home and wait for his call today or tomorrow.
I asked him is my file in their office already and is my background check is completed?he said it seems to him it is completed but he can't tell me more until his supervisor responds.
About my husband case another officer told his case is eligible for interview but interview did not schedule for him yet which we knew about this information,then all of a sudden she asked about my case i told her i have done my infopass a while ago,but she said if i want she can check my case also,i gave my information, first she said my case is alittle bit different with my husband!!!then after more checking said my case is also eligible for interview and nothing is wrong with both cases and we should be happy because atleast they did not forget about our case!!!!!! and our case is moving forward as she can see,she advised to be more patient and wait bacause there are too many cases in this office and etc......!!!!!
Both officer were nice but it seems nobody can tell what is the cause of this long delay exactly?!
I did not receive any call from first officer yet, i am so disappointed and don't know what should i do to expedite our case which i know it is out of normal processing time.
Just wanted to update you guys as i promise and tried to write everything they told us,good luck and god help all of us.
If you have any advice please tell me.thanks
