In February of 2016, I visited the United States. I entered Puerto Rico under the VWP/ESTA. On March 24, 2016 I got married; my wife is US citizen. We started the process for my permanent residency. Four months later, we were notified that the immigration service had denied the the application. Since the 90 days allowed by the VWP had expired, I left the country in September 2016.
Now, after 6 months outside the US, can I go back under the same VWP/ESTA conditions? Is there another way to do it? When I left the US, the permanent residence procedure was still pending.
