I had a similar question recently and called FTDNA.
They told me that they do sell to Israel all their DNA tests.
Why are you looking at mtDNA? Unless you are interested in a very specific maternal line question, most people start with autosomal DNA (atDNA or Family Finder).
I was told that FTDNA sale is coming in August.
Alternatively, you can order Ancestry DNA from Amazon and ship it back yourself.
Then you can upload to FTDNA, MyHeritage, and GEDmatch.
