@Loading.... Just to for the record I by no means say take off your hijab for something as little as visa, my commentary was if you do have one just be prepared for it in regards to your visa 2x2 photograph (apologies if it came out the wrong way). A proper hijab is fine as long as the hairline is showing along with a paper stating that you are wearing it for religious purposes (https://ustraveldocs.com/id/id-niv-photoinfo.asp#:~:text=For applicants who wear a,or clothing obscuring the face.&text=Your photo must be square,the same as its width.) what's not fine is if you have a loosely put on dupatta (as my wife did) that's what will get rejected. I dont have a pic but just image putting on a scarf over your head lol.
@Machinecorpse62 my comment was in regards to the 2x2 photograph. Hijab is fine, I have no idea about burkha I think it's probably okay to enter the embassy, but the CO will probably ask to verify the identity. Also pretty sure a burkha will not work for the passport picture (if it did super easy to scam the entire process).
