I tend to buy refugees since I don't have enough to cover all of the missions I run. I have a list of all of the asylum missions and have started a list of common refugees that match all of the critical traits. For instance

Andoria- There are three perfect refugees (Then Asnelav, Thylos Asali, and Rysva Byls)
Bajor - No perfect refugees, but 3 that have two of the three traits (Urooyo Dran, Zozo Pwin, Ulija Aals)
Benzar - One (Vinac)
Caitan - four perfect refugees (Jhi'lyd Esreb, K'munt, Nuuv, Rylyh Kals)
Earth - Two perfect refugees (Neva Gertrudis Wahid, and Jeffery Toby Lamar)
Rigel - One, Syulag
Trill - One, Nervu
Tellar Prime - Two, Pudo and Doza
Cardasia - Nine - (Slani Kulok, Telen Ghejal, Damin Otek, Jatel Ordel, Milani Ghosen, Nulani Bell, Surjak Mang, Tulor Tulen, Yalor Kel)
Vulcan - One - T'Raalu
Sauria - Three- Rrannu, Mesde and Daamen

I have not found any for Bajor, Benzar, Betazed, Bolarus IX, Caitan. Can you identify any of the missing refugees?

Vulcan - T'Pel and Kaass
Bajor - I just use the Tellar ones (I don't think there really is a perfect match out there)
Betazed - Just use the Vulcan ones

Yeah, BEtazed only has one trait, telepathic, vulcans are the only easy to get telepathic refugees

Bajor wants Spiritual doesn't it? don't Andorians sometimes have it?

Iirc, Bajor wants Spiritual, Resolve and Stubborn. I just fire Pudos at them and hope for something Spiritual I can send back in an exchange.

T'Pel and Kaas hit 3 out of the 4 traits for Vulcan. Are there any refugees that hit all 4?

I also found 3 refugess that hit all of the Cardassian traits; Slani Kulok, Telen Ghejal and Damin Otek.

Bajor wants spiritual, resolve and stubborn. It hates logical

Andor wants Emotional, FF and honorable. It hates logical and unscrupulous

Wouldn't Trill include every Refugee that has Teamwork, since it doesn't really effect success, crit or fail chances if you have more than just that one trait?

Yes, Luchel. i can't remember the name of the female refugee.

there is an andorian male with emotional and aggressive for the caitan asylum.

i think every saurian is a perfect match for the respective assignment, but the problem is getting one.

it doesn't matter whether a refugee has more traits when being slotted for an "one crit trait" assignment (unless one of the additional traits is a failure or disaster trait, which is pretty obvious). although i think that no "one crit trait" assignment has failure or disaster traits.

Do you know the name of any saurian refugees?
