Update on Fall 2021 Application:

I have been an avid follower of this thread for over 2 years, before I began my Master's degree in the US (it's been a roller coaster, but profitable ).
I applied to three schools for a Ph.D. in Earth and Energy Sciences/Geophysics/Geology degree (University of Louisiana at Lafayette, Texas A & M, College Station and Oklahoma State University, Stillwater)

* B.Sc. GPA: 4.59/5.0
* Master's GPA: 4/4
* GRE:311- V 154, Q 157 AWA 4. (written in 2018). Schools waived this due to COVID-19 restrictions and lack of confidence in this metric (depends on the program).
* TOEFL: 105 (taken in 2018 and expired), but I have over a year of graduate school experience in the US.
*1 publication- unrelated research, but a few more publications and abstracts on the way on related research topics.
* 4 grants/scholarships from undergrad and grad schools.
* Over 2 years experience as a GTA and GA (Nigeria and US).
* 4 academic and international competition awards.
* Good volunteering experiences.
* Skilled in relevant software
* Course-related virtual internship
* Over 4 Massive Open Oline Course certifications from reputable schools (Not sure if this was helpful).

ULL- applied in Nov, safe school, admitted in Dec, funding later in Spring. Had a professor interested in working with me.
TAMU - applied in September/October, had an informal Zoom interview with 2 professors in October, got a follow up from the Director of one of their research centers about my research interests. I would most likely be admitted and funded.
OSU - admitted, full and generous GRA/GTA offer (I believe this is an early decision). I have been in contact with a prolific potential supervisor for over 5 months, and hear this prof is a great mentor.

I applied to only three schools because I had been in contact with the professors there who shared similar research interests. I didn't get good replies from the many professors I contacted from the other programs.

NB: Because you haven't gotten a response from a prof. in a program doesn't mean you wouldn't be funded.

Just felt I should post this as an encouragement to hopefuls. This process can be really stressful, especially during the long wait for decisions (Dec - April). But remain diligent, and I assure you that it is worth it. The system works here; your hardwork is duely rewarded, and opportunities are numerous despite being an international student (although it has its disadvantages too ).

Package your application well by highlighting your strengths, take time to carefully review your statement of purpose, ensure your recommenders submit their assessments in time, etc. Also, don't be afraid to contact the program's coordinator if you have any questions (best time is during US work hours).

N.B.: Most Decisions for funding are made between February 2021 until resumption, so don't feel out of place reading my post. Many Fall '21 apps are still ongoing.
Also don't be intimidated by any profile you see online or anywhere. Do your due diligence and hope for the best. Don't underestimate the value of your SOP and recomendation letters.

All glory to God.
Thanks to all the invaluable advice here by generous individuals.
