"Se possível, nacionais."

[alste0]

if nationais is an adjective, the answer could also be "if possible, national" because the sentence does not specify what noun the word "nationais" is referring to.

[donfroylan1898]

agree.

[Frencesca]

you are right, reported

[algrego1]

What does this mean? I don't get it at all.

[JasonPTY507]

Remember portuguese is still in beta, if you see a problem report it.

[jameslucas129]

Could "domestic ones" be an applicable translation for "nationais" in this sentence?

[BobKaucher]

Not really. Domestic is "doméstico" with a pretty distinct meaning.

[moofy]

this one is confusing

[polycrackr]

"Nationals" in this sense makes no sense in English. Unless we're talking BE?

[saniac]

This makes no sense without some context.
