BEIJING — Jared Kushner has said that he has stepped away from the day-to-day business of his family’s real estate company while he serves as a senior adviser to his father-in-law, President Trump.

But Mr. Kushner’s relatives are working feverishly to solicit overseas money for projects in the United States, and they are highlighting their ties to Mr. Kushner as they court investors.

On Saturday afternoon, Mr. Kushner’s sister Nicole Meyer made a pitch to attract $150 million in financing for a Jersey City housing development, known as One Journal Square, to more than 100 Chinese investors gathered at the Ritz-Carlton Hotel in Beijing.

The money would be provided through a much-criticized government program known as EB-5 that awards foreign investors a path to citizenship in exchange for investments of at least $500,000 in American development projects.
