Here is how NumbersUSA characterized a vote by Ron Paul in 1998:

Nearly doubled H-1B foreign
high-tech workers in 1998
Rep. Paul helped the House pass H.R.3736. Enacted into law, it increased by nearly 150,000 the number of foreign workers high-tech American companies could hire over the next three years. Although the foreign workers receive temporary visas for up to six years, most historically have found ways to stay permanently in this country. Rep. Paul voted for more foreign workers even though U.S. high tech workers over the age of 50 were suffering 17% unemployment and U.S. firms were laying off thousands of workers at the time.
