I applied for a US tourist visa in September 2017 to visit my family from Germany that was refused citing the reason under section 214(b): Ties to home country are not strong. I asked the VO about the definition of the home country in my case and he told me it's Germany (where the application was submitted). I was on a student visa at that time.
I would like to apply for the visa again. I am an Indian citizen working as a researcher at the moment and hold an EU Blue card. I have been living in Germany for more than 3 years. I have a good travel history and visited many countries in past for tourism. In the US embassy website, they maintain that I shouldn't apply for the visa again until my circumstances change significantly.
I would like to know if having a full-time job for some time qualifies as the change in circumstances?
Shall I wait for some more time (until I get the Permanent Residence in Germany) and does the time-period between the applications play any role?
I know it might primarily be an opinion based question but still, I would appreciate if I get some comments.
