That Memo by Bo Cooper is still a good guideline. While discretionary and highly disfavored, refugee travel documentation may be issued at a consulate post abroad. If one takes a risk and shows up at one of the US international airports, which is becoming less and less likely nowadays with all the preliminary inspections instituted in the last decade, border control officer will refer you to a secondary inspection at which point you may be, upon the discretion of the ICE officers in charge, paroled into the USA. All of this can be prevented by asking for and obtaining a valid refugee travel document prior to departure. In case of emergency, there are emergency procedures in place which provide for expedited issuance of the travel document.
If you in such a predicament, hiring an immigration attorney is not a bad idea at all.
You should really consult with an attorney to see if the purpose and destination and length of travel would not create an additional issues.
