My husband was on L1. His H1B got approved and we are planning to file my parent’s visa. Can we still file though his status is changed?

When seeking to write an invitation letter for visitors, it is important to document the ability to support the visitor. Current employment should be documented by means of a letter. An Affidavit showing your ability and willingness to support the visitors during their stay would be required. Please also have the visitor clearly document ties to the home country (economic and familial).
