If you have a previously approved I-130 or your immigration status has updated/changed you may elect to provide the relevant I-797 notices to show USCIS clearly what the status adjustment was (this is reported on your application).

We have attached a copy of I-797, you should include 2 pages of this document that shows the relevant details and result (if applicable). The example below is for a person who changed employer while on H1B since they last entered the USA.
