Mortgage lenders typically accept gifts from a different country. However, you'll need to take additional steps to document the gift funds.   The gift can't be a loan; it must be from an acceptable donor, and you must provide the lender with the standard documents, such as a gift letter and proof that the donor transferred the money to you.  In addition, follow these steps when documenting a gift from a different country:
Transfer the fund to a U.S. financial institution.
Convert the currency to U.S. dollars. Exchange rates fluctuate, affecting the funds available for the down payment or closing costs.
Convert all foreign-origin documents to English, such as wire transfer confirmations and documents confirming the relationship between the donor and the homebuyer.
Clear and transparent documentation of the gift transaction is crucial to demonstrate to the lender that the funds are legitimate gifts, not loans.
