Seven years ago, when I was visiting Germany, I met with an official who explained to me t

hat the country had a perfect solution to its economic problems. Watching the U. S. economy【B1】during the 90s, the Germans had decided that they, too, needed to go the high-technology【B2】. But how？ In the late 90s, the answer seemed obvious. Indians．【B3】all, Indian entrepreneurs accounted for one of every three Silicon Valley start-ups. So the German government decided that it would【B4】Indians to Germany just as America does: by【B5】green cards. Officials created something Galled the German Green Card and【B6】that they would issue 20, 000 in the first year．【B7】, the Germans expected that tens of thou sands more Indians would soon be begging to come, and perhaps the【B8】would have to be in creased. But the program was a failure. A year later【B9】half of the 20,000 cards had been issued. After a few extensions, the program was【B10】.

I told the German official at the time that I was sure the【B11】would fail. It's not that I had any particular expertise in immigration policy，【B12】I understood something about green cards, because I had one (the American【B13】). The German Green Card was misnamed, I argued，【B14】it never, under any circumstances, translated into German Citizenship. The U. S. green card, by contrast, is an almost【B15】path to becoming American (after five years and a clean record). The official【B16】my objection, saying that there was no way Germany was going to offer these people citizenship. "Vie need young tech workers," he said. "That's what this program is all【B17】"So Germany was asking bright young【B18】to leave their country, culture and families, move thousands of miles away, learn a new language and work in a strange land—but without any【B19】of ever being part of their new home. Germany was sending a signal, one that was【B20】received in India and other countries, and also by Germany's own immigrant community.
