At this early stage, it is not possible to speculate about the timeline nor the details of each proposed action, so we encourage you to read the official information on the USCIS website: https://www.uscis.gov/immigrationaction, which will continue to be updated as more details are released in the coming months.
Upon the release of new regulations or guidance in areas affecting our international population at UTHSC, we will, of course, provide additional information to you.
