Hello everyone,
I am currently in a bit of a situation with my I-539 (B-2 to F-1) and would greatly appreciate your advice.
I submitted my I-539 with Premium Processing (I-907) listing my brother as my financial sponsor, but after receiving an RFE asking for more evidence on financial support, I realized that my brother (who studies in the US), would not have sufficient funds to sponsor both his own studies and mine. As a result, we've decided to change the sponsor to my father, who has adequate financial resources.
Here are my main questions:
1) Changing sponsors: How can this be done? Would I need to file a new I-539 with updated sponsor information? If so, how do I ensure that the new form is linked to the original one that has Premium Processing? In fact, will the Premium Processing still apply, or would I lose it and have to pay another (really expensive) fee?
2) Currency conversion in supporting documents: Does USCIS require currency conversions from foreign currencies to USD to be done professionally (e.g. as part of the translation or a separate certified document), or can I do the conversion myself while referencing the exchange rate source?
The deadline for my RFE is January 25, and my classes start on January 27, so timing is really critical here – it's crucial that I keep Premium Processing.
Thank you in advance!!
