From our experience, the guards are polite. The officers are polite. The male officer smiled and even joked. He took finger prints and took pictures and collected application forms and ID copies. The woman officer apologized because she had to answer a phone call in the middle. She collected travel reservations and financial documents. She told us to expect 2-3 days to receive passport back and also wished us good trip at the end.There's a copy machine inside the room so you can use quarters to make copies. Also if you don't have the cover letter you can write one in the waiting room. As long as you prepared all required documents according to their website, it's a fairly easy process. A family traveling together only needs one copy of reservations, one returning envelop if all passports to be mailed to the same address. The on-street parking seems plenty. Only complain is that the process took too long. There are about only 10 people before us but we waited about 1 and a half hour. Then 40 minutes to check documents. Even if I already provided a detail itinerary with date and transportation and hotel address, she still checked the reservations and took down notes line by line. Employment letters and pay slips and bank statements were checked carefully and highlighted. There should be a better process of this. In addition, the information on the website can be more accurate. It says only accept credit card for visa fee but the officer actually asked for debit card not credit card. It says two copies needed but actually only one copy was taken, photo (attached to the application form), passport ID page, green card, residence proof, insurance letter, bank statement, paycheck, employment letter, notarized translation of birth certificate (if not in English) etc. Overall experience is good.
