Question 5: AILA members are reporting confusion respecting some of the new questions on Form I-129 as a result of the absence of instructions for those questions. Could SCOPS please clarify the following:
a. Could SCOPS confirm that the Service considers the term “working off-site” – irrespective of where it appears on Form I-129 and its various supplements - to mean working at a client or third-party site as indicated by the instructions relating to Part D of the H-1 Data Collection Supplement?
Response: SCOPS interprets the term “working off-site” to mean that the beneficiary will be working at a location other than the petitioning employer’s work site.
