How does my current location impact my EB-5 consular processing timeline?

Change of location will slow it down, best to continue in your country of residence and I would expect to see an interview relatively soon, but maybe they are doing background checks.

Islamabad is currently experiencing very long wait times due to US visa processing for immigrant visas for neighboring Afghan applicants. Each consular post may have its own internal rules and practices, even setting aside objective factors such as waiting times and workloads. If you have a valid reason to be in a third country, the US Department of State can accept an immigrant visa and interview application at that third country. It is advisable to consult with experienced immigration counsel to map out your consular process, as it is a vital step in your EB-5 US immigration journey.

Different consular posts have different timelines for interviews based on their immigrant visa backlogs. We are not hearing too much about extreme delays in Pakistan or Abu Dhabi posts. Changing the post at this point will just delay the case, it will be just better to stick with the post that you have initially filed with. Generally, we are seeing that you get the interview in 8-9 months after you get the documentarily qualified notification.

I would guess Abu Dhabi is much faster than Islamabad.
