this is what I found....
Will this prove that we DO need the receipt to travel outside the US?

What Are the Documentary Requirements for Travel Outside the United States for H-1 and L-1 With Pending Applications for Adjustment of Status?
Current Service regulations at § 245.2(a)(4)(ii) require that all adjustment applicants obtain advance parole authorization prior to traveling outside the United States. Prior to enactment of the illegal Immigration Reform and Immigrant Responsibility Act of 1996 [IIRIRA], such persons were deemed to be applicants seeking admission and were subject to the grounds of excludability. The Service imposed the advance parole requirement and the concomitant exclusion process in order to maintain control over the re-entry of such aliens. With the phasing out of exclusion proceedings under IIRIRA, however, the Service believes it is now appropriate to amend its regulations to provide fuller effect to section 214(h) of the Act by exempting H-1 and L-1 nonimmigrants with pending applications for adjustment of status (as well as their dependent family members) from obtaining advance parole authorization prior to traveling outside the United States. Generally, such H-1 and L-1 nonimmigrants may be readmitted into the United States in the same status provided they are in
possession of a valid H-1 or L-1 nonimmigrant visa (for those aliens not visa exempt), and the original I-797 receipt notice for the application for adjustment of status, and continue to remain eligible for H-1 or L-1 classification. All other nonimmigrants with pending applications for status must obtain advance parole authorization in accordance with § 245.2(a)(4)(ii) prior to traveling outside the United States.
