Can I apply for a 7-day extension after canceling my Non-Immigrant B visa on March 31?

The user is seeking clarification on the process of applying for a 7-day extension after canceling their Non-Immigrant B visa/M-WP. They inquire about the timing of applying for the extension and whether leaving the country shortly after the extension is granted would be permissible. Community responses indicate that while a 14-day extension is not available, a 7-day extension may be granted depending on circumstances, such as affiliation with BOI or specifics of the visa. However, there is a risk that the extension might be denied, which could result in being issued a 7-day departure notice.
