Can I submit I- 134 after I-864 A ?

[nino1]

Let me explain my situation first . My mom sponsored my grandmother 4 months ago . it was immigration petition and I was Co sponsor . Now my aunt wants to come here with her 3 kids to attend my sis's wedding ceremony . I have couple of questions .

1= Can I sponsor her for temporary visit ? ( remember I was Co sponsor for I-130 , just 4 months ago .)
2= Will I be able to sponsor my fiance after that ? will this sponsor affect to sponsoring my fiance or not ?
3 = Can you plz tell me the exact time period to sponsor another person ?

I am US Citizen and my annual earning is around $ 36000 and I have Almost $18000 in my account ?

I don't think your earnings are enough to sponsor so many people.

The question you need to ask yourself: Can you really take care of all of them financially?
