I applied and received my non-immigrant "O" visa based on marriage and the first issuance was for 90 days, which was entirely in correspondence with what I had read. So I was close to expiration for the initial issuance and went to immigration with all of the required documents and was told that the application would go to Chiang Mai and I was to return in one month to be issued the remaining 11 months of visa. The one month delay threw me for a loop. Is this normal or a red flag?
