Yup.. Only the Family Class application (as far as I know) does an upfront medical. I really don't know how to go about doing a "pahabol" na medical, we have to ask the others who have done the same. St Luke's Extension Clinic in Bocobo is the go to place for medicals. I read that St Luke's in Global City also accepts medicals but I read somewhere here na may pumunta dun but hinahanapan sya ng correspondence from CIC na for medicals na sya (parang they don't have an idea about upfront medicals), and IOM (I think this is in Makati, if I'm not mistaken). Better that you go with the one in Bocobo kasi karamihan dito sa forum e dun nagpamedical.
DM under Sponsorship, I assume? Did you indicate an email address on your application? Kasi email ang primary means of communication ng CIC/CEM with applicants and sponsors. Kelan mo nakita ang DM? Usually, ang Sponsorship Approval email is halos sabay lang ng pagchange ng eCAS status. Check your email and your spam folder.
