Does a PhD expire?

No, a PhD degree itself does not expire; once earned from an accredited institution, it's a lifetime qualification, but the knowledge within it can become outdated in fast-moving fields, and universities often impose time limits (like 7 years) to complete the degree program, not to maintain the earned title. While your earned doctorate is permanent, your status as a student ends, and your research relevance can wane without ongoing work, making you appear "rusty" but not invalid.

How long does a PhD last?

Completion normally requires three or four years of full-time study, or at least five years of part-time study, including a probationary period. Terms of research are normally consecutive and, for full-time students, require residency in Cambridge.

Do you need to renew your PhD?

Anyone with a doctoral-level degree is entitled to the title, but social norms dictate its application, especially differentiating between academic doctors and medical doctors. 

Is a 3.4 GPA too low for PhD?

A 3.4 GPA is on the borderline for PhD programs; while below the typical 3.5+ expectation for competitive programs, it's not automatically too low and can be overcome with a strong application showing significant research experience, outstanding letters of recommendation (LORs), a compelling Statement of Purpose (SOP), and high GRE scores, especially if your performance improved over time. Focus on demonstrating research potential and aligning with specific professors, as holistic review values potential over just grades.
