How long has it been since you submitted your application for AP?

I applied through a lawyer even though most people here file the application on their own and it is probably something I would also do in the future.

I did have a letter that I wrote stating my reason for my travel and relation to the humanitarian purpose I was seeking. However, my lawyer said that it was not required, so it was never mailed.

I applied for AP for humanitarian purpose and all of my documents were in English, but if your documents were in another language, then yes, you would need to get them translated so it's a smooth application process.
