Passage: For a long time Sundar Singh had wanted to visit Britain, and the opportunity came when his father, Sher Singh, who was converted too gave him the money for his fare to Britain. He visited the West twice, travelling to Britain, the United States and Australia in 1920, and to Europe again in 1922. He was welcomed by Christians of many traditions, and his words searched the hearts of people who now faced the aftermath of World War I and who seemed to evidence a shallow attitude to life. Singh was appalled by what he saw as the materialism, emptiness and irreligion he found everywhere, contrasting it with Asia's awareness of God, no matter how limited that might be. Once back in India he continued his Gospel-proclamation work, though it was clear that he was getting more physically frail.

Question: When did he visit the US?
1920,
