I am applying for a spouse visa outside of the US. My case has just been transferred to NVC yesterday. The next step is paying to NVC but I wanted to delay a few months for the process. Basically, I want to aim to be interviewed half a year from now or later. Also, collecting my police record from my birth country will take a few months since I am living in a third country (where I applied for the final interview appointment). So, I was thinking of taking extra time to pay NVC fees and submitting financial documents so that the whole process takes longer than usual. I was wondering if there is a deadline to pay NVC. How long can I wait to pay the NVC fee? If payment has to be done soon, can I wait to submit financial documents? How long can I take time to submit these?
