No you can make all the payments at once 

My case was submitted to USCIS on 26th of September 2019 and got approved on 28th of May 2020 and received instructions from NVC on the same day about account and submitted fee on the same day as well. after I think 5 days payments were approved and on 7th of June we submitted all required documents to NVC and on 17th of June received that my documents were accepted and approved by NVC (Documentarily Qualified). That was my whole journey till now and right now I am waiting for embassies to reopen so that NVC can arrange my interview and medical examination.

Congrats

you will have to wait for few months before actual interview. there are many ppl waiting since Mar. 
 
only you will be able to enter embassy. its the new rule

Congratulations to you. All the best on your interview.

You must bring more evidence of your marriage. Bring chat logs, call logs, pictures of both of you from wedding and after wedding and also bring money transfer receipts. You have to do this and bring with you at interview.

Yeah,  congratulations!!

Well its not Mandatory ,its ok. 

Only you will be interviewed for a visa

I sent my all required documents last week to NVC and today I received an email from NVC and when I opened my account on CEAS and when into the message box I saw this.
So that's mean that my case approved by NVC and now they will let me know about my medical test and interview date?

On the copy of the NOA1 which your wife would have received, it will say in the bottom left hand corner which service Center is processing your case.

For clarity, I-130s 
They lied........average time for a spousal visa, as reported by other VJ members, is 471 days from filing to interview....and it appears that times are increasing.  Pakistan is known for quite long periods of AP.
 

 

What service center is your petition at? Will give you a slightly better indicator of how long it will take to approve the I-130
