<p>Under CIS regulations, a company may petition for approval of a  blanket L-1    visa petition. If a company has transferred at least 5  L-l employees during    the last 12 months it will qualify for a blanket  petition.</p>
<p>In its petition, the US company (Japanese subsidiary company)  describes in    detail the number of multiple L visa positions it needs.  If approved, these    positions are certified for a period of 3 years  and replacement staff do not    need to petition for an individual L  visa.</p>
