I would do some research - attend information sessions online, read blogs, brochures, etc.   each school and program will have tons of information on their websites.
Some of the top PP schools are Princeton SPIA (fully funded and also gives enrolled students a living stipend and health insurance), Harvard HKS, Yale Jackson (also gives good funding).  Other top schools including Columbia SIPA, Uchicago Harris.  It really depends what you want to study and where you want to be.  John Hopkins SAIS has good programs  in DC.  There’s Michigan and Syracuse and many others. 
 
Some programs have application due dates in December and some in January so take that into consideration.  Princeton SPIA wrote on their blog if you apply before October 30th they will waive the application fee. https://spia.princeton.edu/blogs/interested-learning-more-about-princeton-spia-join-us-information-session
Try to get as much funding as you can (Princeton and Yale give great funding), taking out tons of debt for graduate school is not great.  
good luck!

Agree on the above esp. the quant.    
If you want to pivot you might explain why/ what you have done in order to start achieving that goal.  If you write about immigration, have you done anything in your roles? Did you work on visa sponsorship in your previous HR/ recruiting job?  Did you volunteer at an immigration non-profit/ ACLU, etc?  
I agree on GW Elliot and Georgetown Walsh.  Also, look at Princeton SPIA, they give full tuition + stipends to all enrolled students.  Yes, they focus on public service, but if you look at student + alumni bios some have worked at FAANG jobs. Yale Jackson has good funding, too.  
Admissions have in-person and virtual sessions some with just admissions some with students/ alumni/ faculty.  I would attend if you are able even virtual sessions as it gives you an idea of the program. 

with inflation and a possible recession on the horizon I do think for some large graduate school debt might take decades to pay off.  Especially for those who still have loans from undergrad.  Debt also impacts other aspects of your life such as buying a home.  I think it’s something to seriously consider.  
 

 
 

Just FYI HKS does offer a one year mid-career masters as does some other policy schools including Princeton (if you are admitted to Princeton SPIA you receive 100% tuition paid for and living stipend for graduate degrees).  
 
I would look at the classes at each program and do some research on each program by attending sessions they have/ speaking with current students and go from there.  Good luck!

I would recommend working for a few years and applying again to possibly get more funding.  Many of the programs say on their website the number of years they recommend having before you apply.  This will also help you with the job market because you will have experience and not just internships under your belt and that says just as much about your ability as a graduate degree.  Many of the job data these schools have will probably be for students with at least a few (or more) years of work experience.  Working will also give you another network when you leave graduate school which is also important.  
 
The policy and non-profit job market can be tricky and doesn’t pay the greatest especially not for entry level.  I recommend taking out the least amount of loans as possible. 
 
Really think about what you want to concentrate on and then start applying for jobs in that area.  If you have a goal and you demonstrate that through your work experience that is important too.  I know working for a few years seems long, but it really isn’t and it may help secure more funding, get into better programs, and better jobs after graduation.  Good luck!
