US Immigration from Colombia

I am hoping someone has experience with this. My SIL was questioned by CBP regarding pot use and it is in his file. He will be doing his consulate interview in a few months and in preparation for medical has been under a doctor s care in Colombia getting monthly drug tests to show he is clean for the last year (will be 1.5 years by interview date). So, will this front loaded evidence be enough to keep from getting the automatic one year ban and get him approved or if not, what should we expect at the interview?

Hello there. Hope all of you are fine.

When you saw something wrong in your documents for a petition filed online, and you corrected it, do you recommend to submit it in the Unsolicited evidence section, or wait for a RFE?

Thank you

My sister in law has an appointment in Montgomery soon. Are they still doing same day ceremonies? The last report I got was a year ago from a friend. With this getting closer and closer to the holidays it would be nice to know if this will be completed in one day, or if we will need to go back.

Hello.

I saw on some official pages from USCIS that you can smile but naturally with both eyes open. In other posts said that not smile, so, is it wrong or right to smile naturally showing teeth?
