I'm studying two majors: English and German.

[angelene001]

Is it possible to say:
I'm studying two majors: English and German.

Probably it would be better to say:
I'm a student. My majors are English and German.

They are both acceptable.

In the US, you don't "study" a major. You have a major, you study a subject, or you major in a subject. You can also have a "dual major" although I don't think I've heard anyone say they were "dual majoring in subjects X and Y."

I do understand that this type of vocabulary and usage will vary regionally.

Neither have I. Double major, however, is fairly common. For example: I double majored in philosophy and mathematics.

You're totally right. I wrote that early before my brain was in gear.
