Prince Harry's US Court Battle with Conservative Group over Immigration Documents.

Prince Harry's US visa application is under scrutiny in a US Federal Court case brought by the Heritage Foundation, a conservative US-based think tank, which alleges that the Department for Homeland Security (DHS) operates double standards and preferential treatment. The case hinges on two questions in the visa application related to drug use and violation of controlled substance laws. The Heritage Foundation wants a judge to instruct the DHS to unseal Prince Harry's visa application to determine if he answered truthfully, which could lead to perjury charges if he lied. The case will be subject to further legal argument before a judge decides whether or not to release the prince's visa application.
