Could i add you please? Im spanish native speaker, and i would like to help you if you need it. Right now, i need a lot of help with English.

If your mailing address is the same as your street address, I think you can write the information just in the first address field, and in the second one, write "SAME". As for the level of detail required, you should list every relevant piece of information (name of street, number, name of colony, city, etc.). The employer wants to know exactly where you live.

But, have i to write the entire address then? like name of street, number, name of colony, city?

If there are two fields pertaining to your address, one possibly refers to your MAILING address, while the other is for your STREET address. Some people have their mail delivered to a post office, rather than their house. If both addresses are the same in your case, you can indicate that on the form. Good luck!
