some websites OK I485 with only DOS letter

I got this from Zhang & Associates website and am wondering where this comes.


Q: I am in J-1 status and am subject to the 2-year foreign residency requirement. I filed my foreign residency waiver with the State Department but have not gotten it approved yet it by the USCIS. May I still take advantage of this new rule?
A: Once you have received the approval from the State Department, you may take advantage of this new law.

Example: Ryan is in J-1 status as an exchange visitor. He has not, however, filed his foreign residency waiver. Ryan may file an I-140, but may not file an I-485 until he has obtained a waiver of foreign residency.

Example: Cristina is in J-1 status as an exchange visitor, and has filed to obtain a waiver of foreign residency. Cristina may file the I-140 & I-485 concurrently.
