• Americans living abroad file taxes with the Internal Revenue Service, which can cost hundreds of dollars to complete even though about 60 per cent do not owe taxes, according to the Taxpayer Advocate Service
• Those obligations apply to millions of Americans residing overseas – estimates range from 3.9 million to 5.5 million – including so-called "accidental Americans" who are unaware they hold dual citizenship
• The double taxation policy has been a contentious issue for decades, with many overseas Americans feeling that it punishes them for pursuing opportunities abroad
• Unlike most countries, the US follows a citizenship-based taxation system, meaning that Americans must file taxes annually, even if they do not earn any income in the US.

Across most of Asia, people pay for taxi rides, restaurant meals and merchandise with smartphone-readable barcodes — except in Japan, where cash still rules. Now, as the country’s biggest web companies race to dominate the payments market, one Tokyo-based startup says it has a fighting chance to win with its QR app.

Origami had a head start when it introduced a QR-code payment service in late 2015 and has since signed up fast-food chain KFC, Tokyo’s largest cab company Nihon Kotsu and convenience store operator Lawson. The company raised $66 million in September to expand nationwide and plans to more than double its staff of about 100 employees, says founder Yoshiki Yasui.

Origami is betting that stores, which until now relied on direct mail and email newsletters, will pay for the ability to reach customers on their smartphones. For example, a hair salon using Origami’s payment app would be able to send a message to past customers with a coupon for their next haircut.

Quick Response codes, the dotted squares that can be read by smartphone cameras, were invented in the 1990s by a unit of Toyota Motor to track automotive parts. But when the Japanese pioneered digital payments almost two decades ago with contactless cards for train fares, they chose the so-called near-field communications technology. The high cost of rolling out NFC payments, convenient ATMs and a culture where lost wallets are often returned have all been cited as reasons why cash remains king in the archipelago. In China, however, QR codes dominate.

Cashless payments, which includes credit cards, accounted for just 20 per cent of total consumer spending in Japan during 2016, compared with 60 per cent in China and 89 per cent in South Korea, according to a report by the Bank of Japan.

• Canada and Mexico are significant energy suppliers to the US, providing the majority of oil and natural gas imports
• The introduction of tariffs could hinder the US's clean energy initiatives by raising input costs for materials like nickel
• US domestic suppliers might benefit from higher prices, but overall oil consumption is expected to decrease due to elevated costs

The site is part of the Hili archaeological park in Al Ain. Excavations there have proved the existence of the earliest known agricultural communities in modern-day UAE. Some date to the Bronze Age but Hili 2 is an Iron Age site. The Iron Age witnessed the development of the falaj, a network of channels that funnelled water from natural springs in the area. Wells allowed settlements to be established, but falaj meant they could grow and thrive. Unesco, the UN's cultural body, awarded Al Ain's sites - including Hili 2 - world heritage status in 2011. Now the most recent dig at the site has revealed even more about the skilled people that lived and worked there.
