There are dozens of cases where people flying to the US via Abu Dhabi got refused, had their visa cancelled or revoked, and couldn’t even reach an interview. In every case described, the visa was cancelled because of a long stay abroad during OPT, not because of the route itself. The Abu Dhabi route, however, increases the risk: it hosts a CBP preclearance facility, where the decision is made before the flight to the US.

What happened in the cases described

In the first case, a candidate spent 80 days outside the US while on STEM OPT. Her job with the employer continued throughout, and on some days she worked remotely. She tried to return via Abu Dhabi.

At the preclearance area, a CBP officer said she’d been outside the country too long and that, in his judgment, her visa didn’t allow staying abroad that long. Lawyers in this case confirmed that a longer departure is legal if approved by DS. At the border, though, the decision went differently: staying outside the country for more than 60 days was treated as a violation, since STEM OPT requires training and employer oversight, not remote work from abroad.

Her visa was cancelled under classification 212A 7A1. She then applied for a new visa. The interview lasted 15 seconds instead of the usual 45–60 seconds. The officer barely looked at the documents, said she currently wasn’t eligible for a visa, and refused her under section 214B.

The second and third cases

In the second case, a candidate was also outside the US on STEM OPT, this time for 2.5 months. The exchange with CBP was similar, the refusal was issued on the spot, and the visa was revoked.

In the third case, a person had been outside the US on initial OPT for four months, despite already having a job offer. In Abu Dhabi, he was offered the chance to withdraw his entry attempt voluntarily. That way the visa isn’t officially revoked, but he can no longer use it to enter either: the account of the case says the OPT is considered violated in such a case, with employer oversight not maintained.

Why Abu Dhabi is considered a risky route

CBP preclearance isn’t available at every airport in the world. According to the list cited, Canada has ten such facilities, Ireland has two, the UAE has one (in Abu Dhabi), and there’s one each in the Bahamas, Bermuda, and Aruba. Most Indians, as noted, fly via Dubai, London Heathrow, Frankfurt, Doha, and Singapore, where the first interaction with CBP happens only on US soil.

According to the author, two people they know returned to the US 60 days after a trip home and entered without issues; neither of them connected through Abu Dhabi. This is an observation, not statistics, and shouldn’t be taken as a general conclusion.

As the material notes, comparable stories about entry problems at US ports themselves were nearly impossible to find, so the reasons for this difference remain unclear.

What matters for those on a work visa

The material names two rules. First: avoid the Abu Dhabi route when possible. Second: don’t stay outside the country for long on a visa that allows working in the US. According to the author, almost no worker does this on purpose, but these cases don’t arise without a long departure.

If you’re on an H-1B or a student visa, check the conditions of staying abroad with a lawyer or your international office before traveling, rather than relying on a general rule.
