The passenger record you reference indicates that his last residence was in Vienna, not where he was born. Also, that was struck out, and it indicates his last residence as USA. So, that means he had been in the US prior to his entry in 1914. It also indicates that he was married at the time, and he was a butcher by trade.
The 1930 Census indicates he is married to another woman:
Robstown, Nueces Co., Texas
Smith, Frank, Head, aged 40, married, at age 21, b. Austria, parents b. same, Bohemian, immigrated 1905, naturalized, meatcutter
Smith, Jennie, Wife, aged 36, married, at age 21, b. Austria, parents b. same, Boehmian, immigrated 1905
Smith, Frank Jr., Son, aged 17, single, b. Texas, laborer
I found a birth for a child to Francis Schmidt & Edna Hutta, but this is either a second marriage for him, or a son born to Frank Jr.
His WWI Draft Card gives his birth date as January 20, 1888, and that he was born in Vienna; a butcher by trade; it also indicates that he had been in the infantry in Austria as well. Believe it says 1/6 year (ie, 2 months). Dated 5 June 1917 in Waco.
