根据 https://www.gpo.gov/fdsys/pkg/FR-1999-06-01/pdf/99-13759.pdf § 245.2 (a) (4) ii. (C) The travel outside of the United States by an applicant for adjustment of status who is not under exclusion, deportation, or removal proceeding and who is in lawful H–1 or L–1 status shall not be deemed an abandonment of the application if, upon returning to this country, the alien remains eligible for H or L status, is coming to resume employment with the same employer for whom he or she had previously been authorized to work as an H–1 or L–1 nonimmigrant, and, is in possession of a valid H or L visa (if required) and the original I–797 receipt notice for the application for adjustment of status. 理论上来说,valid H or L visa在revalidation的时候不是必要的,所以i485应该仍 然有效。不过这个是个灰色地带,最好还是不要冒险吧。
