how do I know my service center please?

check the receipt letter

if they are scheduling cases that are documentary qualified on June, you will most likely get an interview appointment at the end of this month.

@kalid jamma thanks I was stressing because I thought we will get scheduled straight away

I think your embassy is current which means there is no backlog so they schedule interviews once a month and they most likely send interview appointments the last week of the month so hang tight you will receive them soon.

@kalid jamma thanks bro
