I have received an email from the Visa office requesting me to attend the PDOS and CIIP seminar. I am confused because I still don't have my visa approval or passport request. I've heard that those who are invited to go through PDOS and CIIP seminars has already received their visa approval. They require my medical form as valid document needed for me to be qualified to attend the seminars. I need your advice on this matter. Is this a positive sign, that my visa approval will come soon? Please enlighten me. Thank you in advance for your advice.
