[Sherry927]

Hi everyone,

Case: EB2
Location: Long Island, NY
Interview date: June
Received REF request: July
Mail REF doc to Local Field office: July
Received transfer notice: case transferred to Texas Service Center (8/31)
Received transfer notice: case transferred to National Benifits Center (11/8)

Did anyone have the similar experience?
Not sure what I can or what I should do now.

The I94 (custom stamp from my last entry in the States) is till Feb, 2019.
So if the case hasn't been approved, do I need to leave the States?
ps. I have my valid Visa till 2021, but the custom stamp is only till Feb, 2019.

Thanks.
