Pardon the ignorance, what is a "CSP"?
Corporate services provider.
And do you know any EMIs that are more lenient toward offshore companies?
Revolut,
N26,
Paysera, Wise?
Wise, Revolut, and Paysera do from time to time accept companies from these kinds of jurisdiction.
Currenxie, Airwallex, Statrys, RD Technologies, Statrys, WorldFirst, Fazz, and Aspire can often work if you're incorporated in
Hong Kong,
Singapore, Labuan, or elsewhere in Asia.
Within Europe, there is a wide range of EMIs that have a higher risk appetite. I've listed them before many times. Just to rattle of a few I know to open accounts for offshore companies: Zen.com, Verifo, 3S.Money, GuruPay, Connectpay,
Genome, Sepaga, Klarpay, Nexpay, IBS, Interpolitan Money, Payset, PayAlly, Wallter, Narvi, EcommBX, WireBloom, Intergiro, FinXP, Bilderlings,
VertoFX, and more... Availability varies. Do your own
due diligence.
