It seems that the invitation to our two Syrian families to have their medical exam was sent in error. After the invitation they received this note: "Kindly inform the applicants to disregard the emails they received regarding the medical examination. The International Organization for Migration (IOM) will contact them to book an appointment for the examination in due time." 
This error is most unfortunate as it has raised hopes with the families in Lebanon and Toronto. I hope that a proper invitation will be issued soon.
