It is currently taking USCIS approximately seven months to process an H-1B extension of stay. You may remain in the country and continue employment for up to 240 days while the extension is pending. A transfer can be filed while the extension is pending, but it is best to wait until after the extension has been approved. You can read more about H-1B at http://myattorneyusa.com/work-visas.
