rgding extension notice receipt for visitor visa

[rkh]

Hi
I have applied for extension of visitor visa for my parents and
received the receipt notice I-797 C. In the receipt the *Class* field
is given as RETURNING WKR.I am not sure what this means?

Since my parents are visitng me and not working I would like to know if this is a correct status shown, or do I have to contact USCIS for clarifying/correcting this.

Thanks

Don't worry about it as long as you get new I-94 form.
