At the moment, alien seamen present problems due to a variety of factors: The inability of Norwegian, Greek, Yugoslav, Dutch, Belgian, and other friendly vessels to return to their home ports under German occupation to replenish their crews with nationals; the dislocation throughout Europe of arrangements for hiring, paying, and attending to the welfare of seamen; the inability of American immigration authorities to force the repatriation of Norwegian, Greek, etc., seamen who overstay their leave in our ports; the wage and other labor difficulties arising from the freedom of seamen to accept or reject any offered job, to quit their jobs and seek better ones; and the operation of our Asiatic exclusion laws upon increasing numbers of Chinese and Lascar seamen.
