As much as I want to lash out at the US embassy Pakistan, you have to look at the situation in Pakistan as well. Pakistan has probably the worst recording keeping in the world.
On my last trip to Pakistan I asked a guy, he was poor but still, how old he was? His answer 30-35. Didn’t know what day, month or year his birthday was .
next if you haven’t had your interview yet, the best piece of advice that no one will give you is
give the interview in your native tongues. Urdu, Punjabi, Pashtu, etc etc etc.
no matter how confident your spouse is with English, even if they have phd in English from a Pakistan university they will never be on the same level as a native speaker aka the counselor.
true story: a girl decided to give the interview in English. Midway through the interview she started getting confused and she is can I have the translator now. And the officer just laughed loudly.
listen you can do whatever you want but immigration is a matter of national security and they are looking for any reason to deny you or delay the process.
don’t give them doubts that don’t exist to delay your case bc of misunderstandings due to language. And make sure your documents have same info every where. So if one document have a middle name,
all documents need to have a middle name.
