denied food stamps, many immigrants scrape for meals**In the first wave of welfare cuts to hit New York City under the Federal welfare law, more than 50,000 able-bodied legal immigrants between the ages of 18 and 59 have been denied food stamps since September; Federal officials say law, intended to move foreigners off public assistance and into jobs, has pushed an estimated 770,000 immigrants off food stamp rolls across the nation; while advocates for the poor worry that hunger is on the rise in New York City, few of more than dozen immigrants interviewed recently say they were actually going hungry; instead, they appear to be sliding deeper into poverty; photo (M)
