SINGAPORE - The United States Embassy in Singapore will remain operational, with visa and American Citizen services to be available, despite a government shutdown that began on Saturday (Jan 20).

Appointments that were previously scheduled at its premises at 27, Napier Road, will be honoured, the embassy said in a Facebook post.

On its Facebook page, the US Department of State's Consular Affairs said that "scheduled passport and visas services will continue in the United States and at our posts overseas during the lapse in appropriations".

The US federal government officially shut down on Saturday - the first anniversary of President Donald Trump's inauguration - after lawmakers failed to agree on a stop-gap spending deal.

During government shutdowns, government employees are vulnerable to furlough, or temporary unpaid leave.

Other "essential" workers, including those dealing with public safety and national security, will continue working, some with and others without pay.
