California Rep. Darrell Issa’s bill on H-1B visa allocations heads to its first committee vote this morning. The bill would make it more difficult for “H-1B dependent” companies to obtain the work permits, Axios reports. The new bill would change the threshold for defining H-1B dependent employers — to those with at least 20% of their workforce using the visas from its current 15% — and would also eliminate several other exemptions.
