After submitting the request vs After submitted the request

[firewallengineer]

I’ve read a document and found the following sentences; “After submitting the request”.
My question is what is the difference between these two sentences? Can I use the second one?

1. After submitting the request;
2. After submitted the request;

Thanks

I've seen these structures after "after":
1. After submitting the request.
2. After the request is/was submitted.
3. After you submit/submitted the request.

1. After submitting the request;
2. After submitted the request;

No

You could use After having submitted the request, but the first sounds more natural to me.

3. After you submit/submitted the request.

Thanks moonlike, 5jj, & Tdol for your input. All these sentences are correct right?

Based on my limited knowledge in grammar, word “submitting” in the first sentence is a gerund.
For no 2, “is submitted” is a passive form of simple present.

“was submitted” is a passive form of simple past.
In the last sentences, “you submit” is simple present while “you submitted” is simple past tense.

Please let me know if my analysis is correct or not.
