Alphabet's Google advised employees holding temporary U.S. visas to avoid international travel. The company issued the warning due to unprecedented delays in visa stamping at U.S. embassies and consulates.

Wait times for visa stamping now extend up to 12 months in some cases. This delay creates a serious risk that staff could be stranded abroad and unable to re-enter the United States for an extended period.

The internal memo targeted staff holding H-1B, F-1, and J-1 visas. This guidance underscores the growing challenges foreign workers and their employers face amid significant backlogs in the U.S. visa processing system.
