They need your 3 pictures, 1 inside working place with other staff members, one picture of your office building and one pic of your office front with company logo/name. This is what they asked from me at the time of applying my work permit.
And what if I never had any receipt? they didn't give me any receipt when I got my first extension, I had been traveling in and out since I got my first extension so never went for report but now my date is due tomorrow. My first ever 90 days report
