During my stay in the states my passport got expired and I had to get new from DC. With the new passport I left Newark last month for Kathmandu. When I arrived in London I realized that the airport authority did not keep the I-94 which I had enclosed in the passport, and I could do nothing at that time. Later I came to know that one has to submit I-94 form before leaving United States and for not doing so matter can be complicated at the port of entry. I did give them the form but the officials did not care that. Now I’m worried and i have no clue what should I do. Your suggestion will be very helpful for me. Thanks.
