Chinese millionaires turned away The Convention Center board says the money presents too many issues.

Close to 150 Chinese millionaires want to help Philadelphia expand its Convention Center, but the center's board wants no part of their cash.

That has left the potential investors more than a little frustrated.

For the Chinese, the money represents a legal way to expedite access to U.S. "green cards" for permanent residency. Adhering to the requirements of a nearly 20-year-old federal immigration program, they have each plunked down $500,000 in an escrow account at a U.S. bank.

For the state, that money - $73.5 million - could be a cheap way for the Convention Center to borrow funds to cover some of the expansion's construction costs, which are projected to surge over the $700 million budgeted. (Under the loan program, the money would be repaid, over five years, at a remarkably low interest rate of 2.5 percent.)

But for now the Convention Center, as cash-starved as it is, has no interest in the foreign funds.

"We considered it. We looked at it. But it was kind of a bridge too far . . . too complex for us to consider," Buck Riley, chairman of the 15-member Convention Center Authority, said last week. "Right now, it is a dead issue."

Another board member said the board was hesitant to get involved with what seemed like "immigration policy."

Known in Philadelphia as the "Welcome Fund," the little-known loan program has been administered jointly since 2003 by the Philadelphia Industrial Development Corp. (PIDC), a city-related nonprofit economic-development agency, and CanAm Enterprises, a New York firm that has structured immigrant investor deals since 1987, mostly in Canada.

PIDC identifies potential borrowers; CanAm seeks out investors. Approved investors receive conditional green cards.

Within two years, they become eligible for permanent green cards, if, among other things, their money spurred jobs. Under the Philadelphia program, 10 new jobs must be created for every $500,000 invested.

To date, the foreign funds have helped pay for 21 projects in Philadelphia totaling $148 million. Among those receiving investment dollars are Comcast Corp. ($26 million), Temple University Health System ($13 million), August Aerospace Corp. ($15 million), the law firm of Duane Morris ($6 million), and Stephen Starr's Continental Mid-Town restaurant ($3 million).

"We owe $33 billion of debt on our balance sheet, so if we have an opportunity to borrow some money at 1 or 2 percent, yes, we're going to do it," said Comcast executive David L. Cohen.
