Premium Processing has an SLA of 15 Calender Days, Provided U dont run into RFE
Ur Wife can go for H4 Stamping if ur H1B is Approved. She just need to fill DS 160, pay the fee, book the appointment and attend interview, result will be told then itself and the passport will be received before a week
If U verify the case in USCIS, u can see email word instead of mail if its Premium Processing
Now my case status is moved to RFE yesterday and am not seeing any email word, i see on uscis case status " we mailed a notice requesting additional evidence or information in this case I129 PETITION FOR A NONIMMIGRANT WORKER.", that means mine is a normal process.
Once after moving to RFE how many days it will take after our employer respond to that notice ?
