I just went today and there was nobody to talk to. Even the website is not clear with wht is needed for the visa requirements for an internship less than 90 days. I was told my the security guard that the office on the other side will help me with my inquiry but when i went to the other office, the lady sent me back to the other office. I was just dancing back and forth between the two offices and nobody was ready to answer my questions! I was very disappointed! Nobody picks up the phone as well. I have been trying to call them from the past 1 week but it always goes on voicemail. I have been tired doing it.
