*Navigate through IVR (1, 1, 1, 1, 1, 1, 3, 1).
*IVR will ask your application id. Don't wait for it to ask for 3 times before it routes you forward, just press # and it will instantly ask for your year of birth in 'YYYY'. Put the year of your birth.
*IVR will tell you the waiting period before your call can be answered by an agent. Or if the call traffic is too high, it will ask you to call again later.
*As soon as you get to the agent, just ask for the UCI#. They do not have any status information for FSW applications. Agent will ask for your last name, first name and date of birth. After some seconds, you will have your UCI#, if they have started processing your app.
If you get quick with the IVR, you can reach the waiting period (point# 5 above) within 2 minutes otherwise it may take around 6 to 7 mins before you are asked to wait for an agent.
