Hallo Thea,
Evert Ridderinkhof left the port of South ?, England on 21 November, 1920 on a Norwegian ship. He arrived in the port at Norfolk, Virginia on 21 December, 1920. It appears he may have been a "fireman" on the ship; in other words, a part of the crew.
On 28 December 1920 he declared his intent to become a citizen of the USA. On 3 August 1921 he became a resident of the state of Maryland, living in Baltimore. He was a carpenter.
In 1921 he petitions to become a US citizen and applies for his naturalization papers. He was living at 841-1/2 West Lombard Street, Baltimore, Maryland. He states that he is single and was born on 25 October 1897 in Kampen, the Netherlands. His last name is officially written as "Ridderinkhof" but it is noted that he is also known as "Evert Rider".
