I want links or a link to companies that I can purchase insurance from
only to cover pregnancy complications (not maternity delivery
charges). The risk of those complications is extremely low, and I
think insurance companies would not mind insuring that. But I want to
ensure that those insurance do cover major pregnancy complications,
and of course, would allow pregnant women to be insured (some of them
consider them ineligible. I have no fee limit or other considerations.
Can pay as much as needed. I am in Washington DC, and I am a foreigner
on a one-year valid visitor visa.

Thank you for your question.
 
I believe that to answer it well, your question will require more time

HI Velid-ga,
Search with "pregnancy risk" insurance  and you will find lots of sites.
Not all of them offer insurance coverage, but others talk about the
risks, which proobably is also of interest to you.
Take care!
