Thanks Alexander Cheberk for the MMT VISA extension summary!

Points learned today vs other sources, etc

Only 1 copy of the documents.

TM30 not required.

Printed out USA embassy letter was ok. Got the embassy letter next day at 8:10AM.

Nobody asked for the online appointment doc.

Form STM2 - they asked me to redo it and complete it in front of them, 2nd floor.

GPS - I drove and parked at the roundabout. Possible parking in the back but the front gate was closed.

Got there at 1315 to the small exterior tent.

Confusion... just sit in a chair and wait.

Called up to the 3rd floor parking garage, highly suggest sitting on the far right row of seats, 5 rows 20 deep. I sat in the 4th and it took an hour before moving to the 2nd floor.

When leaving the 3rd floor, all 5 rows full again.

2nd floor took an hour, checked documents, got a number, 600ish.

1st floor - zero questions asked. Took my 1900B. Went to another queue and waited for the passport.

3 hours total.

Rain smashed down and 3hr return trip.

No taxi cars waiting when I exited but they were there when I arrived.

Would suggest showing up closer to 3 or early and sit in the right side row.

Sept 23 with Oct 21 stamp.

Told I could come back for renewal.
