The application process was easy. I received my visa quickly. But I had problems printing it. Apparently a Windows 10 issue, so Visa HQ should make sure that the file is compatible for common software platforms. When I called Customer Service to understand the printing problem, the agent had no suggestions. When I asked if I could show the visa on my phone if I couldn't print it, the agent was very rude, saying that he had never been to Vietnam, so how would he know if electronic vs print would be okay. I replied that VisaHQ is supposed to be an expert on visas and they should know if I can use an electronic version. He just basically told me it was my problem. Finally able to print on an Apple. A lot of people don't have multiple machines.
