<p>In the past, foreign based companies could fill their employment needs with    E visas alone. Therefore most Japanese aliens had E visas. Since many foreign    based companies have relied on this visa in the past, some of them resisted    the use of other types of visas.</p>
<p>However, since it is becoming increasingly difficult to obtain the desired    number of E visa staff, the strategy should be reconsidered. In the future,    the wise managers will use all the visa categories available to fill their personnel    needs in the U.S. Therefore, in the future, it will not be uncommon for companies    to have a mixture of E, H and L visas on their U.S. company staff. Also, some    E, H, or L alien employees might apply for and obtain permanent residence. This    is clearly the trend and those companies that resist this trend may encounter    difficulties in completing their local staff.</p>
