The term Change of Status (COS) is the name given to the process through which a person can change from one temporary status (nonimmigrant) to another temporary status without having to leave the United States. Typical examples of this process are changing from a student visa status to H-1B. Usually, a successful COS is evidenced by the USCIS issuing you a new I-94.
Changing status from a temporary visa to a green card within the United States is also a change of status, but it is technically referred to as Adjustment of Status (AOS).
The US State Department has made the following announcement today regarding the phased resumption of visa services.
What kind of problems can employment-based nonimmigrants (H-1, L-1, E-1, E-2, E-3, TN) face during reentry?

Here is a question from our clients-only extranet.
I am reproducing material from our employers-only (by invitation only) conference call for tomorrow. These matters need to be in place for H-1 new applications, transfers as well as extensions.
I have received e-mails from folks about my 2009 articles on immigration law compliance and end-client letter issues in H-1B cases published by American Law Institute - American Bar Association. Here is the link:
