My Interview Experience (CR-1) May2, 2007 @6:30am:Rob (my husband) and I woke up at 330am and got ready for the interview. We went to the USEM at 435am (14th-15th in line). Rented chairs while waiting near the waiting shed.
5am-
Security guard checks for the
appointment letter and ID, then we went in for another line just outside USEM.
6am - We were allowed to go in the USEM premises. Then we were given
ticket number/stubs (6013). 730am- Number flashed to go to
Window 26 for the pre-interiew. The interviewer is a young Pinoy.
- He asked me for my BC and MC.
- He asked me what was wrong with my BC since NVC forwarded them a copy of the Court Order's Decision I sent to them with regards to my BC correction of entry. He told me to show the CO the original copy of the court's decision.
- He asked for Rob's W2 and ITR (latest).
- Then he asked for photos, emails/chats and cards (I gave him 2 folders for that).
- The he asked me when, where and how Rob and I met? And he asked Rob where and when we got married?
- The pre-interviewer was so nice, he told us to take a seat and just wait for the final interview.
730am- my name was called at
window 16 for the finger scan.
815am- number flashed to go to Window 28. The
CO is a young Asian guy who is always smiling and laughing and is really a very nice guy.
- He asked me about the Court's Decision and I told him its just a typo error and he said "Oh, its nothing" and he gave me back my copy.
- He asked where and how we met? When Rob first came here? And why it took that long? And Rob answered because of his job and its the busy season and he can't just take a leave.
- He asked Why we got married at Puerto Galera and I told him it was Rob's choice and Rob elaborated and the CO was nodding.
- He asked how many attended and if I would have wanted more to attend? I said around 30-35 and Isaid no, because that would be more expensive.
- He looked at the pictures (and there's so many of those I prepared) and he saw my family and friends and Consul sounds happy while Rob was explaining about those pictures (even if I already placed captions with those pictures).
- He checked Rob's ITR/W2 and then he saw a business permit and he asked Rob: "So, you have your own business?"... And Rob said yes. Then CO said: "Oh, so everything looks fine"... and he gave me back the photo, emails/chats/card folders and Rob's Affidavit of Support Folders.
- I asked:"Are we approved?"
- He replied: " YES" (with a big smile) and said to wait again to be called but not to buy tickets yet.
- Interview with CO took only about 3 minutes tops.
830am: Name called to
window 37. The lady gave me back my appointment letter and stapled a pink slip and told us topay Delbros and just wait for about a week if within Manila. Rob asked if we can have it picked up? Due to the excitement, Rob forgot to ask CO if we can do that.
Then we
paid Delbros. Lady told us to wait about a week (more than a week if outside Manila).
We are back at the Hotel (Mabini Mansions) 9am!!!
I received my
visa after 5 working days in San Pedro, Laguna.
GOOD LUCK on YOUR IR-visa Interview!
