just posting to say my wife and i applied for and received our non-immigrant single entry O and ED visas from the kathmandu, nepal embassy in 3 days’ time. it was a breeze, the wait was next to nothing (walk ins only, no appointment) and the processing was super fast. it may help that it is the off-season in kathmandu but worth considering for some visa purposes (it is a more expensive trip than laos or KL)
