Sir citizenship government approve karte hai unka decision or discretion hai so time frame decide nahe kar skta for you it would be better ki ap dusri country mai jakar shadi karo fir marriage ka ground per unka visa India mai apply karo.

Dear Sir,

Citizenship of India by naturalization can be acquired by a foreigner (not illegal migrant) who is ordinarily resident in India for TWELVE YEARS (throughout the period of twelve months immediately preceding the date of application and for ELEVEN YEARS in the aggregate in the FOURTEEN YEARS preceding the twelve months) ...

Nahi aap special marriage Act or Sharia law se shadi Kar sakte hai

For Pakistani citizenship its not so easy to get Indian citizenship after marriage also. She can come her on tourist visa and again can go back. 

Further one more option is to get her converted into Hindu. And than apply for Indian citizenship 

In case a marriage between an Indian and a foreign national is to be registered in india , generally its required to file a notice of intended marriage with a Marriage Registrar in delhi . That notice is required to be published for the stipulated 30 days. At the end of the 30 days the Marriage Registrar is free to perform the marriage.
The notice of intended marriage can only be given in India, if at least one partner is permanently and the other partner temporarily resident in India.
After the stipulated waiting period of 30 days the marriage can take place in India. Under the Special Marriage Act, 1954 a certificate showing the signatures of the persons married, the registrar and the witnesses will be issued. This Certificate is required as proof of the marriage and when applying for a visa to for a foreign country.
The following documents are required for both the partners: a valid Passport, original Birth Certificate showing parents' names,
if the person concerned is widowed, the original death certificate of the deceased spouse
If divorced, copy of the final decree, documentary evidence regarding stay in India of the parties for more than 30 days (ration card or report from the concerned SHO). 

1. A foreign national marrying an Indian will soon not have to stay put continuously for a year in India before he or she can apply for an Indian citizenship.
2. The new proposal is that the law be suitably amended to allow for a foreigner to be allowed breaks for a total period not exceeding 30 daysduring the prescribed period of one year stay in India before he or she can make an application for Indian citizenship. Foreign nationals marrying Indians presently cannot leave India even for a single day in the one-year prescribed period before applying for Indian citizenship.
3. Rest, you can contact me through Kaanoon for knowing detailed procedure for the same.

You can get married to her, if you have attained 21 years of age and she has attained 18 years.

Agar woh India aa gayee to Indian authorities usko arrest kar lengi kyunke woh yahan bina bataye aayegi. Isse acha yeh hai ke usko Dubai le jaayo ya kisi aur country aur wahan aap marriage kr lo..uske baad wahan se Indian consulate mein chale jaana aur register karwa lena..uske baad citizenship ke liye apply it dena.
