以前我在这里问过这个问题，很多人都说这样回去会自动取消485的申请。其实不是这样的，我问了我的律师
又在USCIS的网站找到，H签证并没有这样问题。
Advance Parole
Most aliens who have pending applications for immigration benefits or for changes in nonimmigrant status need Advance Parole to re-enter the U.S. after traveling abroad. Aliens applying for advance parole on the basis of a pending application for adjustment of status must be approved for advance parole prior to leaving the United States in order to avoid the termination of their pending application for adjustment. Note: this does not apply to aliens who have applied to adjust to permanent resident status and who maintain H-1B (Specialty Worker) or L-1 (Intracompany Transferee) status, or their dependents, who have applied to adjust to permanent resident status and who have valid H-1B or L status and valid visas, V nonimmigrants who have a valid V nonimmigrant visa, are in valid V nonimmigrant status and have or obtain a valid V nonimmigrant visa before applying for readmission to the US, and K-3/4 nonimmigrants who have applied to adjust to permanent resident status and who have a valid K-3/4 nonimmigrant visa, are in valid K-3/4 nonimmigrant status and have or obtain a valid K-3/4 nonimmigrant visa before applying for readmission to the US.
