Updates can be done online via the FMCSA online registration system with your US DOT PIN, or by filing an MCS-150 form.
See below for more information on updating your US DOT number information.
Q: I have a sister who is a US Citizen, and I am an F1 student, wondering if it would be possible to apply for green card through my sister, and how?
You are required to provide this update every two years even if your company has not changed its information, has ceased interstate operations since the last update, or is no longer in business and you did not notify FMCSA.
There is no need for a separate application for your son.
Your son can come to the US now on the B2 visa and then wait for the application to be approved and do an AOS.
IEPs are unable to perform an online update at this time.
Download the Intermodal Equipment Provider Identification Report form (MCS-150C) and complete, sign, and date the form, and mail it to the address above.
