I think the bill does so in two respects: It stipulates that when application is made for a visa. the issuing officer shall examine all evidence at hand and shall ascertain whether the person applying for the visa and seeking admittance to the United States Is affiliated with any organization that is known to be engaged in subversive activity. and whether such person seeks to enter the United States for the purpose of attempting to overthrow our Government by force. If so. the Issuing officer is to refuse to permit the admittance of that person. although. of course. that Is not the case today.
