Vo: sorry what ? Kept checking my passport . Oh ok visit visa then he looked which countries passport is it.
Vo: so you are applying for f1. He didn’t knew what documents to ask for f1. Kept looking on a list pasted on a wall to check which documents are required, then he was reading my ds-160 on his screen for 5 min.
Vo: your I-20
Read it for few min then Asked me

He didn’t asked for bank statement neither I-797
Vo: you are approved
I was shocked that he didn’t asked me much.
Me: thank you sir, will I get a receipt or an email . He responded but I was so happy I didn’t understood what he said.

September 16: got an email to submit ds-5535 which is background check and comes under extreme vetting.

September 18: got passport back without visa and a 221g yellow slip

My status used to update 2-3 times every week. They always sent me a general reply to my emails.

Left for Pakistan on October 12

I use to email them 1-2 times a week

On October 29 I called nvc and the lady was so cooperative with me I told her my classes have already been started since October 8 so how long it’s gonna take.
She said email your consulate with your passport and wait for them to reply

30th October got email from consulate that someone from department is reviewing my file
Next day got an email to submit passport.

November 4 flew back to Canada and sent passport. After 11 days it got updated and next day got an email that my visa is issued. Got my passport back next day.

Struggle was still pending.

On Montreal airport

Custom officer: do u have green card
Me: no I have f1 visa
Co: how long u r living in USA
Me: 1.5 years
Co: What’s your status in Canada
Me: visitor
Co: so u went to USA in b2 and later got f1. What was your intention when u entered USA first time
I told him that I went as a tourist got impressed with educational system and applied for cos bla bla bla
He kept questioning and then took me to a room where more people were sitting before me.
After 15 min my name was called and he said on your I-20 classes started 6 weeks ago so why u r late. I explained him that my visa is issued 2 days ago and it’s not my fault. My I-20 is still valid. I was then being told to go back and have a seat

After 30 min another officer who was so kind and chill told me that I’ll be with u in a minute then he called me in his room and told me to explain everything from start. He then said to slow down and let me him write everything.

I was being told to provide any evidence that my collage will still accept my if I m 6 weeks late even tho my I-20 is still valid.
anyways he even tried to call college but no one was there in Saturday morning 7am

He said my story is good but I need to have any email or any prof other wise they can’t let me go and I’ll have to come back on Monday with a prof.

I was trying to find my dso number from my cellphone where he asked me to have a look of my cellphone. He went through different apps and asked about different names from my WhatsApp chat and who they are what they do, he also took my phones imei number and noted it that’s it.
Officer: you are very kind with me I don’t wanna stop u but unfortunately can’t do anything. I can talk to my supervisor but cannot promise
Me: will u be in my side,
Officer: I’ll be on both sides but will surly tell him that u r nice guy
After 5 min he came back and said decision is now on me so I’ll let u go, u r a nice guy I hope u will not ruin anything when u go to USA.
Took my details where I’ll stay.

Officer: next time it will not happen with u but always have a proof. Good luck
