Hi, Recently my L1 blanket visa was renewd and I travelled to the US. The embassy had provided me only one copy of the stamped i129s back. At immigration the officer asked for it and kept the one copy I had. I asked him to give me a photocopy but he refused. Now the visa says i have to present the i797 /,i129s for entry to the US. How will I present this now in the future?
