Reapplication for 30-day extension of overstay amnesty using embassy support letter: last I saw ppl were being told to return mid-month, 11th? Is this still the case? How long does IB consider Emb Supp Lett valid? Mine is dated 1 Sep. Is it better to go now, log a visit and be told to return or wait? BTW props to US consul getting these letters out very fast.
