On mixed marriage. The man is a born again Christian, while the woman is a baptized Catholic. Can they marry twice, that is, marry at both the Born Again and the Catholic Church?

No, the provisions of Can. 1127 § 3 forbids a couple to marry twice in both churches. They can either marry in the Catholic Church or in the Born Again church.

In the event that they chose to marry in the Born Again church and would like to have their marriage acknowledged by the Catholic Church, they could ask for a Dispensation from Canonical Forms BEFORE the celebration of their wedding in the other religion. Please contact the Chancery Deparment for more information.

For couples who are already civilly married , is it necessary for the foreign partner to secure legal capacity or embassy clearance in order to marry in the Catholic Church?

There is no need for legal capacity or embassy clearance, but a certified true copy of the civil marriage certificate is necessary.
