Hello! Can someone help me with this?
Is it a correct sentence or not?

The process of visa application begins with filling out the right form under the right category. The small mistake can cause a negative effect on the result of your current as well as in future applications. Instead of filling out a visa form in confusion, it is better to take the assistance of experts.
Abc(company name), the team of specialists are always here to help the prospective visa candidates to fill out accurate information.

Thank you in advance

Ask a friend to help you fill it out and get them to check through it.

Hello !
This is a future spammer trying to get their grammar correct.
After all, isn't that what tips you off ?

sentence number..:
1) Use "in" instead of "under".
2) Should start with "A" not "The".
3/4) Needs rearranging completely, something like this:
It is important to supply accurate information on this form. Please ask ABC for assistance as required.

Some may argue that you fill in a form rather than fill out, though both are acceptable in this context.

Visa applications need to be correctly filled out, any mistakes can have a negative impact on the result. ABC have a team of experts at hand to help you achieve this.

Sorry, sentence 2 should probably be replaced also:
//Any errors or inaccuracies may effect this and future applications//

affect, not effect.
