It looks like Johan Friesen crossed the boarder into Washington state twice. The first crossing shown was 30 Sep 1939 at the age of 22. His departure contact was F, Jacob Frieson. The arrival port was Sumas, Washington. The second crossing shown had an arrival date of 10 June 1940 at the age of 23. Same departure contact, F, Jacob Frieson, and same arrival port, Sumas. Do you think that Jacob Frieson is Johan's father?
