It is becoming increasingly difficult for people – particularly those from the developing world and the global south – to move around the globe. The UK voted “yes” to Brexit. Donald Trump wants to build a wall on the US border with Mexico. Hungary is also mulling a wall to keep “outsiders” from crossing its borders.
The attitude of citizens in higher income countries towards immigrants is hardening. Visas are harder to come by, no matter the purpose of your travel. And, as research we conducted in late 2015 reveals, scientists from the developing world are among those caught in the cross hairs.
Barriers to travel
As part of the research we conducted an online survey to examine the impact of visa requirements on scientific collaboration. Some of the respondents were postgraduate students; others were active researchers and academics in fields like biology, earth sciences, applied mathematics and engineering. In total, 232 people representing 46 citizenships – from Canada, Chile, France, Malaysia, New Zealand and Kenya, to name a few – took part in the research.
We found that researchers from countries defined as developing by the International Monetary Fund perceive current visa rules as a major impediment to professional travel. Their peers from developed countries did not experience visa rules as a significant barrier.
