Facebook plans to provide free WiFi connection in 35 locations across Greece, as well as to continue working with the UN to give people in refugee camps free access to the internet. Plus, the company will use its website to raise funds for them and to donate funds to NGOs catering to their needs. As for Microsoft, it plans to help NGOs provide wider access to education and training. The company also wants to build an Innovation Hub, where refugees can develop their technical and entrepreneurial skills.

HP has a similar plan, with the aim to build six Learning Studios in Lebanon and Jordan for kids and adults. The same goes for Coursera, which will team up with NGOs to give refugees access to over 1,000 courses offered by universities. Since some refugees still need to learn English or to brush up on their vocabulary before they can jump into learning skills, Zynga is making an educational version of Words with Friends. The social video game-maker will also provide experts to mentor the finalists of a competition that aims to create an app that can teach Syrian children to read in Arabic.

Uber's and LinkedIn's projects, on the other hand, will benefit those looking to start working ASAP the most. The former will team up with resettlement agencies in the US to offer refugees work opportunities, while the latter is expanding its refugee initiative called Welcoming Talent to countries outside of Sweden. The other familiar companies in the list are IBM, Twitter and TripAdvisor. IBM promises to continue supporting European refugees and migrants any way it can, while TripAdvisor has already earmarked $5 million for humanitarian organizations. Finally, Twitter is giving NGOs in the US and Europe a $50,000 "Ads for Good" advertising grant.

In the White House's Call to Action months ago, the administration stressed refugees' potential to contribute to the countries they fled to if given the opportunity. The companies that decided to pitch in could open those windows of opportunity that might remain close otherwise.
